"Don't slutshame. Sex isn't meant to have kids. Children are an occasional side effect of sex."

I could say a lot here--I don't want to go off on a tangent about how to discuss things that are inherently shameful, and how shame is not a social construct--but I will restrict myself to this:

If conception is an accident, a rare coincidence, then why is failure to use contraception in 100% of sexual encounters (y'know, just in case it's that one occasion) described as "not being responsible?"
