That's not just my environment, that's the point. A lot of people, no matter where they're from, their education, their "class" (if we want to use this term) have to deal with all sorts of malice directed at them on a daily basis, with women, people of color and lgbt people being the most vulnerable. It's a systemic issue, you telling me I should voice my opinions more often, which is what I'm doing right now, without suggesting ways on how to educate other people to be more welcoming of those opinions, sounds more like a parent who has to teach a child to defend himself, because an idea of teaching kids not to be violent towards each other doesn't even cross other parents' minds.
The media isn't some sort of a god, it cannot create a demon out of someone who absolutely isn't one. The fact that Trump just keeps succumbing to all sorts of shit, minor or not, and just "allows" the evil media to twist it against him just proves how undiplomatic he is. This kind of behavior opens up more than a million of possibilities to manipulate him into any kind of thing you want, you mentioning it's more important with what kind of people he surrounds himself just proves that. I'd argue that given the modern political climate, having knowledge in politics and history is more than welcome. It's ridiculous to suggest otherwise, of course, technically it's not required, but in this way you're just putting yourself in a favorable
place for others to eventually eat you alive. Or shit all over everything on your own, you can pick one.
Besides, going back to sexism, when people offend each other, we have to go deeper, to the roots of such offence. A one time occurrence may not necessarily mean you're evil, we're all human after all. But if it goes on and on, even if it's directed at an individual, rather than a group of them, where does it stem from? Ignorance? I would argue such excuse can only be valid for subtler situations, like being oblivious to minor cultural sensitivities because you'd never really been exposed to it before, or being ignorant due to your environment, upbringing, which is sexistic. You couldn't choose your upbringing, but the people who before you may have. Or the generation before. You may not act out of your personal hatred, but if you go back throughout history that may have affected your environment, you'll find a cause for this. It's systemic. If it's supposed critique of an individual that supposedly has nothing to do with the qualities of that person that can't be changed, and if it keeps repeating, even if it's a different individual, you have to ask yourself whether it's not so sexistic after all. You might hate someone because that person is dumb, or you might dislike someone because of their looks, but if you keep noticing a pattern in others over and over again, and you act on it, be it a rude joke or something more vile than that, maybe it would be the perfect time to admit that the problem lies in yourself rather than those people. Does this still not count as sexism?
