Why is physical labor bad to you Mr. Author and Mr. Poster? Why would a young communist think physical labor was bad?

I think a big part of this is a generational stereotype thing, that the young people (millennial or younger) are the privileged ones, and that the youth these days are allergic to “real” work, the kind of hard work the boomers had to do… while being able to afford to buy a house and raise a family on a single income, which young people could do to if only they were willing to work hard for it and give up their avocado toast. It’s totally ass backwards like everything else about this meme, but I don’t think that one aspect of it is even a dig at communists per se, it’s just boomer humor disparaging people younger than them and especially students. I’d bet most of the lemmitors upvoting that would actually balk at the implication that only boomers know about “real” work if that were the only thing the meme was about, but because it is also anti-communist, they’re all for it.

So much :projection: my eyes are burning in their sockets

That’s exactly it. It’s not just the typical intentional misunderstanding of communism, it’s a denial and reversal (projection) of who actually has the privilege when it comes to labor.

Part of it is that physical labour fucking sucks under capitalism because it incentivises working long hours in dangerous conditions, so a lot of people end up crippled in one way or other before they can enjoy retirement.
