I've never met one. But when people find out, you are vegan, everyone starts shoving their expertise, defense, aggression or at least either the fact, that they don't eat meat that often or that they could not live without meat and that its their genetics basically making their body NEED meat and that's why they crave/eat it.

Just like those Christians

Vegan Bullshit Bingo #7:
Veganism is like a religion
That sounds like an attempt at discrediting Veganism as unreasonable and irrational, just to not seriously deal with it. As Veganism is based on facts, logic and common sense, it is the exact opposite of a religion. Consuming animal products though, mostly means blindly following irrational traditions and ignoring the facts or refusing them by reasoning: "That's how we've always done it". That sounds more like a religion to me...

that try to force religion down your throat.

Vegan Bullshit Bingo #48:
Vegans are forcing their opinion on others
Fortunately we have freedom of speech. Opinions and actions can be criticized. Especially when the critique involves valid arguments. As consuming meat is legal, vegans aren't enforcing anything. Much rather, we are seeking education, and an open dialogue about the topic. This is unfortunately often jeopardized by a lack of proper counterarguments and the allegation we would enforce our opinion. Eating animals though, forces others to captivity, violence and death.
