You may not have liked McCain politically, but it's probably best to keep quiet about intimate things such as his romantic intentions or past relationships, your comment is sleazy and cheap, and I'm almost certain you're not an authority on those aspects of his life.
Great example of inversion right there. What McCain did to his first wife was sleazy, reminding people of it is not sleazy. This is the #metoo era, we are all moral absolutists now, particularly in the treatment of women.
Of course I am not an authority on those aspects of his life, doesn't mean I can't speak about it or have an opinion about it. This is after all a discussion forum, which by its nature should encourage alternative views and opinions.
I like McCain, I voted for him twice (primary in 2000 against Bush, and again in 2008 against Obama). I even liked Palin, before she self-imploded.
