I'm a guy who's shy, a bit introverted, very awkward due to anxiety, and I'm only 5'6" and 120lbs. Because of that, I'm a victim, so that's why I hate modern feminism.

You aren't a victim unless you are 120lbs because you don't have legs.

Because of modern feminism, I can't complain about being lonely. I got told that I am "entitled" to women, just because I say I'm getting frustrated with the pattern of women seeing me only as friends, and nothing more.

No, you get told that because women don't want a guy who has less muscle with them.

Because of feminism, I'm bullied due to my nerdiness. I get called entitled, misygonist, etc, just because I'm starting to get bitter.

Because of your nerdiness, you're bullied due to your nerdiness. You get called entitled and mysoginist because you think a girl should jump on your dick for no reason.

Because of feminism, I'm told that I should lower my standards, even though my standards aren't too crazy high. (I got told by a girl that's below average who goes out with below average men, that she just sees me as a friend).

You think you're above average or something? You shouldn't worry about standards anyway, girls create thousands of reasons for a man to not be good enough. All you can do is make yourself better.

Before feminism, I can just make my good salary, and women will settle for me. But because women are making equal to men now, I have to lower my standards. I wish it was back in the day.

You think you can't do that now? You can, and trust me, it's a bad idea.

Even though I'm liberal as shit (I like BLM, Bernie Sanders, and other liberal causes), I have a seething hatred of feminism. So why should I like feminism if I've been a victim of it?

You should like feminism because it makes it easy to spot and avoid crazy girls and you definitely shouldn't hate it seeing as how it has nothing to do with your problems.
