1. I don't recall the blow job meme becoming overtly sexist. Is it sexual in nature? Sure. Is it demeaning to women? Hardly. Sexuality is a beautiful thing that many coeds begin to explore. If Thunder gets to receive or give oral over the next 4 years, good for him. Not sure why talk about sex is so offensive in certain parts. It's something that nearly 100% of adults do from time to time. Why is talking about it so offensive? I'm not sure anything said in the posts has objectified anyone.
2. The only vaguely sexist posting lately has been the talk about ESPN's Mendoza. I think it's obvious that some people are much harder on her than her cohosts.
