I only used the "eat meat" example because the guy I replied to did. A better one, IMO, would be "arguing against companies having to pay taxes because the employees already pay income taxes". My CEO has said something akin to that on multiple occasions and I'll keep challenging him on it because I strongly disagree. That doesn't mean I expect him to change but I do expect him to defend his standpoint.

There's nothing wrong with challenging people on different topics, lots of healthy and fruitful discussions can come of that, it's just the "don't be obnoxious and entitled about it" part that seems to not resonate with some people but I think that's an entirely different issue.

Is this sarcasm or have you never met vegans?
