Those memes. Posted mostly by insecure people who claim they are okay with how they look or how they are, but in fact are insecure about it and want others to validate them by agreeing with the meme.
The worst ones are the "real men" or "real women" ones.
Real Men like Real Women with curves. Etc. Or some variation on that theme and starting point.
In my world, all men are real. Men like women. Unless they are gay. Then they like men. Some like both. Women like men. Unless they are lesbians, then they like women. Some like both.
Some men like curvier, heavier, shapelier women. Some like skinnier, firmer ones. Most men like any woman who looks good within her own body shape and are willing to have sex with them. Because, most men want any woman who is attractive and will have sex with him.
This whole real men and real women thing is just stupid. Real stupid.
Baskin Robbins has 31 flavors for a reason. We all like different things. Doesn't make one better than the other. Doesn't mean anyone is fake or real for having those preferences. Accept who you are, and who others are, and start being real. Not real stupid.
