"You just don't love yourself" is probably the most disgusting and irritating phrase to me that has ever been spat out by a pro-lifer. If it's relatively easy to come up with a laconic counter-response to something else.
For example:
Pro-life: It's a temporary problem
Counter: Life is really temporary
Then this phrase just... It just terribly amazes me with its stupidity, vagueness and total lack of understanding. Tell me, how the fuck can anyone not love themselves? Someone who spews something like this really believes in the holiness of the very fact of being alive, that depriving oneself of such "pleasure" can only be harmful, and if a person intentionally harms himself, then he doesn't love himself.
Of course, I can guess where the roots of this saying come from. If we assume that some person takes care of himself, has a healthy lifestyle and strives at all costs for self-development, someone on an intuitive level can try to characterize him as someone who loves himself. But a person who drinks, smokes, eats fast food and plays games and watches movies/anime instead of working/studying, then they say he doesn't love himself, continuing this logic
But here's the truth of life, all living things are designed in such a way that they never consciously strive to harm themselves, at least they never think that they are harming themselves. A person who doesn't take care of himself and has bad habits, loves himself just as much as the first one and acts for his own benefit - satisfies his needs and doesn't burden himself with what he doesn't need. And of course it's the same with suicides. No one kills themselves because they want to make things worse for themselves, but just the opposite, they do it because of the relief and unbearability of further life. It's just that some people are not able to think in such categories as "life that is worse than death" for them death will always be worse than any monstrous life, such as my parents, for example, and all of the above is why I recently had a quarrel with them the other day.
