I have experiences with this too. Sometimes my dad shares me these shitty facebook memes and one time it was about abortion, it was something along the lines of:
"look the father and mother have both STDs and all their 6 kids are disabled!! But wait!! Dont abort the baby!! Cause Beethoven's family was like that!! IT COULD BE a GENIUS!! You just ABORTED BEETHOVEN!!!"
-_-
I called him out for the antiabortion bullshit and turned out he only thought it was funny cause he knew about Beethoven's family history sigh. He fucking shared the shitty meme without even thinking how bigotted it was. LIKE HOW?! How dont you realize how antiabortion that shit was?
And he defended himself with: "but you know Beethovens family was like that..." AAAAGGGGHH
I dont get how these people dont realize how bigotted these memes are. My dad isnt even prolife... and he still didnt bother to think before sharing. "I just thought it was funny"
For fucks sake dad. Think before sharing -_-
