to Those Leftists™, anyone thats left of them, right of them, or has identical political beliefs on everything except one issue are “libs”, its been thrown around so much on lemmy that it takes up the same part of my brain as “woke”, when I see someone use it unironically its generally safe to say I can ignore them.
The dude on the bottom commissioned various artists to draw characters buying wonderbread, eating wonderbread, attending a theme park dedicated to wonderbread, as well as other things involving wonderbread that I can’t quite remember, thus earning the moniker “Wonderbread dude”
Don’t forget the whole issue of the “(non sexual) drag acts are pedophilia” “being gay/trans/etc is child grooming” “Kissing someone of the same gender in a public space should be illegal” arguments that would allow conservatives to sterilize/chemically castrate anybody lgbtq or gender non-conforming due to the whole “Think of the children!!!” moral panic.
