Immediately stomp an insect when they see one inside the house. It's like a reflex or impulse and honestly it's kinda scary seeing an otherwise nice person just stomp an insect or spider or whatever in cold blood almost instantaneously. There's like no thought or contemplation, it's just see the insect, and then immediately stomp it.
Like holy shit what did that little critter do to you? Just let it be.
EDIT: Holy fuck the responses. I guess many didn't actually read what I wrote. I wrote that people who "immediately stomp" without "thought or contemplation" have fash tendencies and I get accused of fashjacketing. Ugh whatever. To those who had thoughtful responses (e.g. if you feel something stinging your skin and swat it with your hand, or if you have an infestation issue in your house, etc.), I gotta say those make sense and I hear you all the way (and even in those cases it's not like there's a kneejerk intentional kill response, it's usually accidental or done after careful deliberation). But to the ones complaining about fashjacketing, maybe do some self crit for fuck's sake. You sound exactly like the fucking man vs bear defender types or a white fragility type, Jesus... It makes me actually think you do have fash tendencies tbh.
One of the (many) things that gives me a disconnect from someone is when I have to explain to them why they shouldn't kill a random bug that comes across our path. It's like, I don't know how to explain that maybe it's not cool to just kill any living thing you see because it's "gross" or you just don't like it.
I've got my own learning to do too, though, with many things. But it is disheartening.
