Seriously? I’d rather slap you with a fish than eat one.

“I’m vegetarian. I mean, I eat fish though.”
Or, better yet-
You- “I’m vegetarian”
Them- “Well you eat fish don’t you?”

The sad thing about this is it means people are stupid. The good thing about the first one is that being vegetarian is “trendy” enough for people to lie about it because they think it sounds good. That’s better than people just going “Ew, of course I’m not vegetarian. Those people look sickly and sad.” Now that some of the most glamourous people on earth are veggie they want to be in with the cool kids.

The second one is more difficult to deal with. It actually means that those people can think of so few vegetables that they think fish might need to be put in the same category. You get this all the time, don’t you?-
“You’re Vegetarian/vegan? What do you eat?”
Like you’re just gonna be like,
“Oh god, I’m so hungry. All I’ve eaten for two days is air. Luckily I can eat fish tonight so I don’t starve and die.”

The people who say these have never cleaned a fish or they’d realize the eyeballs and guts kind of differentiate it from vegetables.
