and of course, computer scare

Killing animals and consuming their flesh is taught to have been a traditionally masculine role. Don't think about how almost no one in most of the world still hunts for their meat, or how the animals are raised.

The same reason any man gets considered "less masculine"

are deeply insecure

"I eat meat because I want to be strong as an ox"

"Ox eat grass"

Real men don't care about lives, not even their own

Because the meat industry has made a decades long psyop to make us associate meat with masculinity.
It started all the way back in the 50's where we invented "cooking, but for men" (grilling). Here's an essay that says it smarter https://www.vox.com/the-goods/2019/6/28/18760073/barbecue-grilling-men-stereotype

Edit: Oh wait you shared an article, I thought you were asking a question lol. I can't see wether posts link to anything on mobile.

It's all projection.

Disappointing liberal article. Advertising did not make something from nothing; gender disparities in meat consumption are older than that. Check out The Sexual Politics of Meat, which answers this question in great detail. It's complicated, but basically:

1. Women are objectified, reduced to specific aspects of their flesh instead of considered as entire human beings. Tits or ass?
2. Animals are literally objectified; a neatly packaged grocery store steak has no relation to the once-living cow it was cut out of.
3. This "absent referent" allows cultural violence against a group without directly recognizing them. For instance, a number of restaurants have animal logos with (human) female secondary sex characteristics that attempt to seduce the patron into eating them. They may joke about chicken "breasts" or "racks" of ribs, etc. Women describe being treated "like a piece of meat"; boomer humor explicitly compares the bodies of women to those of animals to be consumed.
4. Participating in this process is manly, because a man is someone who dominates others by objectifying, fragmenting, and ultimately consuming them. Refusing to turn animals into flesh, instead recognizing them as moral entities, is linked to a refusal to objectify women, instead treating them as people; this makes you gay or a soyboy or whatever.

Please forgive my clunky explanation; I read the book last year. I highly recommend it: it's an easy read and chock-full of evidence.

Commodity fetishism. Using meat as a masculinity fetish, worshiping the inability to have regular bowel movements.

It's just an outdated cultural signifier. If you think about it, most things that associated with being "masculine" and "feminine" don't make a whole lot of sense, and are usually associated with sexist beliefs or with historical things that don't really hold anymore. If we see gender as something that is performed, then eating meat, being angry and hairy and not caring about your health and looks are masculine signifiers in our deeply sexist society.

It's just a manifestation of a society based around consumption. Buying meat from a store and eating it affirms the imagined masculinity that was previously upheld by hunting.

Because most people don’t realize how many vegan men theyve met.

Vegans is woke libs. Woke libs is not manly. Also 4chan soy brain worms.

soy phytoestrogen scare

Because soy has plant estrogen in it or someshit

Like the article says, "It could be a longstanding cultural association that connects meat-eating with hunting or hunters", which is just like when your average chud buys chopped up pieces of animal that someone else already killed from a supermarket.

Less cholesterol, less man. That's science.
