I guess I shouldn't be too surprised about most of the responses to this thread considering it is a anonymous board on the internet, especially since it's Letsrun... but I have a few things to say.
Before you post or get offended about Veganism, do some research on what it's really about and why people choose to live that way. There's this thing called the Google and it makes it really easy to do this.
If you're deriving your manhood from what you eat or do, then you might have bigger issues. If being a man means living a sort of lifestyle where you have to be "tough" and eat and do certain things, then why would you want to be a part of that? Don't let that limit you.
There's absolutely a Vegan stereotype of someone who will tell you that they're Vegan and why and judge you for it. Like any stereotype, they don't apply to everyone. That being said, try to separate the movement from the people. Every group has extremists who don't speak to the true message of the group. This should be a two way street.
