It was 8 years ago. Trump had just been a liberal turned conservative at that time. And Trump has used far more incendiary and inflammatory words than what Vance said. Mean Tweets, anybody.
Bottom line - if you are gonna close your mind on Vance for who he was - just go all the way and hate Trump also.
That was 9 years ago and I’ll also add the H word thing was a private message to a former friend and it sounded sort of like he wasn’t serious, he was joking. Then his friend turned on him and leaked a screen shot to the press. No big deal.
