Did someone actually say something as idiotic as that to you? :S
About 4 or 5 months ago, on campus, there was a random "feminist" (I use this term very loosely, because most feminists push for REAL equality, not "unfair compensation advntages") march that got disguised as a protest against domestic abuse. A good cause, if it weren't instead a lame male-bashing fest. I was walking to the building on campus with the ITG machine in it, and this group (about 50-60 or so) happened to be marching past the same location in the opposite direction. Long story short, one of the people in that group, whom I've never met before in my life, tells me I'm a rapist by default. You know, that 2nd X chromosome gives you the ability to know more things about other people than they know about themselves, that's for sure, because I don't remember ever raping anyone. Even metaphorically. I just ignored it at the time, then went into the nearest building and punched out a trash can in frustration.
I've had similar experiences with a couple "choice" employees at my summer lifeguarding job. One specific example was, during a storm, one of the employees (who was about 18 at the time) was bragging about how she would always sneak into bars with her older sister's (the manager at the time) ID. And the bouncer didn't care, because "all men are stupid." Normally I'd lash out with a diatribe, but I wanted to see where this was going. She then proceeded to brag about how she "never bought a drink in her life" because she was moderately attractive and "men are stupid." I heard enough and went off about how I'm not stupid and how SHE'S the stupid one for breaking the law to leech a couple drinks and that I'd NEVER buy her a drink on merits of aesthetics alone because I am not attracted to the physical beauty of women, in general. She then proceeds to tell me that I'm "no different than anyone else" and that I'd buy her and everyone who leeched off me drinks in a second. One constant with women who think they're better than me by default is that they all think they know me better than I know myself. This basically turned into a unintelligible shoutfest after that.
For the record, I doubt I'm even hitting bars when I'm 21. For one, I'm probably not attractive enough to get past the bouncers. And even if I did, I certainly wouldn't be buying random people drinks, because they're the kinds of people I have no interest in getting to know better anyways.
In conclusion, there's really two kinds of people in this world I can never get along with: People who overgeneralize others, and people who give the people who overgeneralize others a foundation for overgeneralizing others. Reverse sexists are just one specific example of this. Condescending religious nuts are another I mentioned... I guess someone like Jack Thompson falls into yet another category... Jesse Jackson (Everyone's racist against blacks. Even other blacks.) is yet another... The list is so long it would be a waste of time to type further.
On another note, a LOT of today's commercials anger me. They're either incredibly stupid, incredibly insulting (see above: a current trend is the "men are stupid" form of advertising that seems to reach out to the ever-increasing population of jilted single mothers), or just flat out annoying. Then again, I notice this trend with a lot of new movies, TV shows, "music" "artists", etc. Pop culture is just going completely down the toilet nowadays.
Come to think of it, MaxVance's assessment is looking rather accurate.
