I don't know why you're being downvoted. Hart refused to apologize, claiming that he had already done so. Yet there is no evidence that he actually did. He made a statement that could loosely be read as an apology, but that's about it.
What you've described is a form of mindfulness meditation. This advice is applicable to virtually any aspect of life, not just meeting women. OP is a windbag, but the second TL;DR basically sums up the whole post.
It's not merely a man being condescending to a woman, it's being condescending because she's a woman. Obviously both genders are equally capable of being condescending in general, but there are still plenty of men who are condescending to women just because they're women. It's not nearly as bad as it was in the 60s of course, but that mindset still exists, especially in the South.
Mansplaining is indeed a sexist term that shouldn't be used, but the issue of men being condescending pricks to women is not uncommon. Trying to use sexism to fight sexism is retarded though.
I certainly hope SRS gets banned because they deserve it, but I really do doubt that mensrights will get banned unless they start fucking with other subs or people outside of reddit.
