Well of course some people have a terrible relationship with their parents, but I think it's fairly obvious that OPs post is not addressed at them. If your mom was manipulative or abusive to you as a child, and you don't talk to her anymore, nobody's expecting you to call her today.
You have my complete agreement on all points.
You don't have to like to respect.
And you don't have to be familiar with a situation at all to give advice on the Internet!
And, parents being human, sometimes even respect can be lacking.
