Diet Loopholes

Whether you consider it a diet or a lifestyle, I really just don't understand:

Why would you go vegan just to make exceptions for your vegan diet?

To be clear; I went vegan for health reasons (so many) and now I am encouraged to stay vegan for health, environmental,  and ethical purposes. I also just like it. Anyway. 

I recently watched a few youtube videos on the topic and I just find it so bizarre how people will try to make exceptions for this diet/lifestyle as SOON AS THEY CHOOSE IT. Or, possibly more aggravating; when the people around the vegan attempt to create loopholes for said vegan.

For example:

"Oh, you're vegan? Well did you know that you can still have mollusks? Mollusks don't feel pain. So you can have those, y'know."

Gee, thanks, can I?

"Well, I'm vegan for ethical purposes, so I don't see anything ethically wrong with eating off of my omnivore friend's plate if she's full. I mean the damage is already done. I was curious to see how it tasted."

DUDE.

If you went vegan for ethical purposes, that probably means that you are disgusted with the meat/dairy industry / the way that they treat animals / the fact that people are even eating animal products. Why would you even want to eat something that was created from that misery? Animal products are not even food to me anymore. You might as well fill a plate with actual garbage. I find it completely loony that a vegan (of any kind) would even think about consuming something like that regardless of whether or not the damage "was already done". 

Beyond the aforementioned; that scenario just perpetuates the stereotype that veganism sucks / it's impossible / incomplete / not as good as being omnivore / it's okay to cheat / one's cravings (selfishness) is more important than their principals. 

Why do you even want that, little vegan? Gross. 

I don't mean to be too hard on anyone in particular, but if I didn't mean to be hard on anyone, I would never have stood up for myself / gone vegan in the first place. Also: without taking the animals into account, why would you even bother adopting a diet / lifestyle jut to make exceptions? That's ridiculous. And I mean making exceptions on purpose. Consciously. It's a different story if a splash of butter falls into your tofu scramble at the restaurant while no one was paying attention. Accidents happen. 

It's just as bad as those people saying "oh, I would love to go vegan, but... eggs, dude."

As if prefacing in that manner excuses them, somehow. You'd miss flavor? Cool. That's a great reason to not do something that better aligns with your principals. Maybe it's because I just don't get it. I don't feel the same way. I missed burgers, so I ate a veggie burger. Of COURSE it's not going to taste the same, but it's something incredibly similar and it actually tastes so much better (in my opinion) and doesn't leave you feeling like a goddamn mess after you've eaten it. I've never been the biggest fan of eggs or cheese, but after eating a tofu scramble in the morning or cashew-cheez on my nachos? I'm pumped. There has not been a single food substance I have missed that could not be met or surpassed by the vegan version thereof. 

At the end of the day, for whatever reason, 

I

do

not

want

to 

ingest

animal

products. 

That's it. no exceptions.
