I'm wondering if the downvotes are from me not citing sources or from people getting triggered.
If you want to make a statement like this, don't bother unless you have evidence.
It's also usually better to frame it around the evidence, like "this study from UCLA found that higher consumption of animal products led to decreased testosterone levels". This way, the discussion will be focused on the evidence or the conclusion you drew from it.
Not really - for example most “manly-men” can agree heavy drinking decreases testosterone levels.
This is something that baffles me. The biggest, strongest mammals are herbivorous - elephant, bull, bison... Even the best carnivorous animals meditate for a few hours and seek divine help before messing with these guys.
Why is eating grass, not a manly-man activity?
