>Why do foids and normies get so angry whenever I mention that I don't want to have relationships and sex against my will?
Because having relationships and sex is participating in society, if you have never done either you are basically considered an outcast, even if you have a social life. It is considered very anti-social to not participate in these, even the most introverted anti-social faggots are considered more normal than you if they have relationships.
By quitting you stop being an asset of normalcattle society and start paving your own path.
What's unfortunate is that you have to participate in it to continue your bloodline
