|Sorry buddy, gotta say that while the premise is correct that language influences people and vice versa... getting upset over the word
mankind means you're just an unhappy person. Happy people don't go around and say people think of pregnant women with the word
gestation therefore society is evil and unjust. The cold hard truth is, some people will always find something to be upset about. You give in to this, soon there will be something else.
For instance, assuming a boss is a he is being way too over-sensitive. A real female employer shouldn't be that sensitive anyway. There are real problems to solve in the world. In time, this will naturally change anyway.
Let me give you a for-instance of what some call unfair. I'm a redneck from the south. At first glance some people will assume that means I'm stupid (waiting for a joke here lol). The vast, vast majority of people will never learn enough about a subject that doesn't directly involve them. It's human nature. So, there will always be stereotypes (which do have an element of truth but I digress).
So, I could say... the world is evil and unfair or whatever because some people will assume I'm stupid because I'm a redneck. Or I could just man up (I'm so evil lol) and get over it. We have real problems to solve and this nitpicking only harms humanity because we lose focus.
As an aside, there are more women who don't mind taking the last name of their husband and believe in traditional roles. You cannot discredit the majority because the few wants to get upset. I'd never marry a woman who didn't take my last name and every last one of them know it. And there are a ton of women who respect a man for being an old-school man because they're tired of having to always lead the relationship and do everything. I've talked to so many women who are tired of feeling like the guy because the guy is too afraid to be a guy. The younger generation is so confused because rotting behind a computer inside doesn't help produce hormones naturally.
