I answered your comment because it was purely about gender, nothing political, and because the claim about social media posts being a major barrier was nonsense.
Yes, there are political underpinnings to eating animals. I assume you're American, so here's a gallup poll for the US:
https://news.gallup.com/poll/510038/identify-vegetarian-vega...
Since this is about America, it's about right vs liberals (so not left), and indeed they're 3 times more likely than conservatives (9 vs 3%), and indeed women are 2-3 times more likely than men to be vegetarian/vegan (6 vs 2%).
But we're talking about tiny, tiny percentage points. It's the same across the entire West. So singling out men, or even conservatives, for a tiny difference feels like antagonisation with no basis, and your comment reads not like arguing for climate or animal welfare, but as fighting your culture war. And everyone outside of your bubble will see it for a weak attack and dismiss it as just a vehicle for your favourite flavour of bigotry.
Hence why dropping it would have been better.
As an aside: women are the vast majority of leisure travellers (>70% for all travel, and much higher for leisure only). Women are probably 99% of consumers of fast fashion, and the majority of consumers of smartphone updates. The gap is much starker, and seeing it as a culture problem would be justified in discussions about pollution (though not socially acceptable...). But if you were talking about, I don't know, the externalities of coffee production, and women/liberals drank 51% of coffee and men/conservatives 49%, and you complained about women, I'd also just dismiss your comment as bigotry.
