It used to be about dietary issues.
The vegan lifestyle wasn't what it was 5, 10 years ago, it's been warped into the culture what it is now. Vegan lifestyle was not about endorsing the usage of animal products. This includes diet. You'd never wear leather or wool. Vegans were few and far between.
Now, it's just a movement to bully people into wondering why they aren't a vegan too.
All vegans can do now is argue about animal abuse but forget how ethically sourced meat and dairy actually is harvested.
This is just my opinion, but I'd rather save the planet we live on rather than some petty farm animals that aren't even sentient. If you're going off the basis of abuse, what about plants, wheat, grass? - these lived too.
