It’s strange that he feels the need to tell everyone they need to deal with the fact that he was born a man and identifies as a man when nobody has a problem with that.

Imagine someone saying “yes, I like pepperoni pizza, deal with it.” Like, uh, okay, it’s one of the most popular pizza ingredients. Extremely uncontroversial opinion, there. Compare that to someone saying something like “yes, I like pineapple and anchovies on my pizza, deal with it.” While it still may be odd/cringey to wear a shirt saying that, it’s at least a controversial opinion.
