What’s up with people talking about the Talmud on women, gentiles and stuff?

I’ve seen people cite Talmudic excerpts to prove the “evilness” of Jews, portions on women, gentiles and etc with all sorts of horrible stuff.

The rebuttal tends to be stating that it is removed from the context and needs to be explained by a scholar.

How do I verify who’s legit here. Can non-Jews read and study the Talmud? What if I’m a polytheist idolator? Would I be allowed?
