I fully support Christian Walker’s decision to speak out about his father, Herschel Walker. Why? Because I also had an absent father and I understand his internal conflict.
First, if you're not familiar with what is going on, please hear it from Christian directly on this thread:

Not everyone can understand what it's like to go through life trying to love a parental figure who doesn't seem to care about you through their actions.
I would go as far as saying the worst feeling I had as a child was realizing that my father doesn't care about me.
I would get maybe a phone call or two a year from my father asking me how's school for about 5 minutes and then he'd speak to my mother. He lived states away but when he would come to visit, it was because he happened to be making a business trip in our direction.
He would stay for a couple of nights but never really interact with me. He'd be gone all day doing business and then sleep with my mother at night.
What always hurt was that my father would never say goodbye to us because he'd leave in the middle of the night.
The older I got, the less he interacted with me. The last time I saw him was when I was 16. The last time I talked to him I was 21 and I called him. He had no interest so I stopped trying. I never ignored his calls because he never tried to contact me.
When my father died, I felt nothing. I didn't cry. My father died years ago for me. I sought therapy to deal with the neglect from my father and I spent years trying to become the man that he was supposed to make out of me.
I understand where Christian is coming from as the son who is trying to love someone who is highly flawed but he's still your blood. Especially as sons, we want to be like our fathers and we want to be accepted by our fathers.
But what do you do when they've rejected you most of your life? Christian's situation is compounded by Herschel's fame because now everyone is judging him as to how good of a son he is. He's getting pressure to support a man who never fully supported him.
I could only imagine how angry I would be if my father decided to run for office and portrayed himself as this Cliff Huxtable family man meanwhile I'm still picking up the pieces from the emotional turmoil he left me in. Why should I support him when he never supported me?
Christian stated in one of his videos that his father is making a mockery of him and his mother and he's absolutely right. It would be a slap in the face to gloss over the pain he caused Christian and his mother for years just so Herschel can once again come out on top.
People are generally forgiving if you own up to your mistakes and attempt to make amends. Despite what my father didn't do for me, if my father was still alive and called me to apologize, I'd hear him out. Life is complicated & no one is perfect.
I'm not Christian or in his household but I could only assume that Herschel has never done this. Likely, he's been lukewarm in his apology rhetoric & actions following it. This is speculation but I would imagine if he did the work, Christian wouldn't be as angry.
Also, Herschel wouldn't have felt the need to lie about his faults from the past. If he owned up to his mistakes & claimed to take a new approach in life, we wouldn't be having this discussion. But he didn't, he chose to exaggerate & overshadow his son's pain.
For you guys, Herschel is this potential Senator but to Christian, no matter the status given to Herschel, Herschel will always be the father whom he's conflicted with. He doesn't hate his father, he's disappointed in his father for hurting him again but this time publicly.
Thankfully, most people cannot understand the internal conflict of trying to love someone who continues to disappoint you but I do. I know grown men who are still trying to reach out to their neglectful dads. We want to be the good son but we're also trying to protect ourselves.
The most valuable thing I could ever imagine would have been a phone call from my father telling me he was proud of me and actually meant it. I'd still take that today despite everything we went through. As I said, it's a complicated internal conflict.
So, yes. I fully support Christian saying his piece. I get it. I hate that he has to go through this publicly but he's standing up for himself and his mother.
If you want to get mad at someone, get mad at Herschel for being a shitty father and lying about it.
I agree with you regarding their relationship but it seems that Christian was a strong advocate for his father until the abortion story came out as an October surprise. (Yes, I know it was a rumor for a long time but his accuser stepping forward is new.)
I don't know if I believe the allegation yet since I know neither party or owe either my trust. I'm just glad I'm not a Georgia voter.
I watched Christian’s video. He seemed sincere in his hurt. I am cynical enough to believe that his dad told him he was going to be honest and then politics as it is...for whatever reason it didn’t happen. Just sad.
