Sympathetic ear: Uh, because as a human being you should be doing those things in the first place, and OH YEAH: nobody has to have sex with you, and probably won't want to because it's obvious you think basic decency is sex money! To be clear: you are trying to trick people into thinking your Niceness is generosity, when they can clearly see your transactional intent. It's gross. Stop acting like a Nice Guy.
A common stereotype is that EVERY unsuccessful nice guy must be misogynist or whiny, hence why he doesn't succeed. Oftentimes, the biggest proponents of this view are pretty whiny, judgmental, and very pointy-headed themselves. There are many unsuccessful nice guys out there that have external problems in their lives which prevent them from being interesting. They are just looking for like everyone else, but are held in a negative light by those whiners.
Whiny internet nice guy critic (on blog): YEA WELL MUST U HATE WOMEN AND ARE SUPER WHINY ALL U DO IS COMPLAIN, COMPLAIN, COMPLAIN I MEAN I, ME, AND MYSELF NEVER WINE AND AM XTREMELY TOLERANT AND NONJUDGMENTAL. WOW YOU WANT LOVE, YOU JUST THINK WOMEN OWE U SHIT
Unsuccessful genuinely nice guy: I believe you're being judgmental. Maybe you should get off the internet, breathe fresh air, quit making assumptions, and quit provoking people. Not everyone has it as good as you. Good day.
