I'm sorry, but if you eat meat - you are not a vegitarian. And no, flexitarianism isn't real - that's called being an omnivore. amirite?

I'm guessing this applies to peskatarians as well.

I had to look that one up, but I personally belive so. If you eat animals, you are an omnivore. If you do not eat animals, you are a vegitarian - not when you don't eat some animals. If you do not eat animals or eat/use their byproducts, you are vegan. So, if you decline red meat, but eat chicken - you are still an omnivore, the chicken is meat too. If you do not eat poultry or red meat, but still eat seafood, sorry, still an omnivore, fish is still an animal.
