Choosing to not have kids yourself, for whatever reason, is definitely not eugenics. I don't even get how you'd come to this idea.

yes. and to be clear, it’s not eugenics to make that choice yourself. problem starts as soon as it becomes about others though. seen far too many internet conversations go from

• “i won’t reproduce” to
• “it’s my responsibility not to reproduce” to
• “it’s our responsibility not to reproduce” to
• “the poor and disabled should be sterilized.”

this post is already getting pretty damn close to step 3 right there. reddit was awful for this so i encourage us to just be aware when stuff like this comes up.

Alternately: choosing to reproduce for genetic reasons. Positive eugenics is still eugenics.

Historically, eugenicists have attempted to alter human gene pools by excluding people and groups judged to be inferior or promoting those judged to be superior.

Emphasis mine, though seems people rarely get called out for the latter.

I meant that in a 'no woman would want me' way and not in 'I don't want to propagate my genes' way.
