Like your not just wearing plastic and still play on your phone all day thinking being a keyboard warrior helps anyone, let alone animals. Laughable at best and pathetic at worst. Rot faster and you might helps worms
So this is Cognitive Dissonance. Cognitive dissonance is when you're trying to hold two sets of values in your mind at once, like "I'm an environmentalist" and "animal agriculture is terrible for the environment, but I love eating meat and wearing leather". When this happens the feeling is so uncomfortable that you have to do something to release the tension.
For example from "Very Well Mind: What is Cognitive Dissonance"
"Some things that a person might do to cope with these feelings include:
Adopting beliefs or ideas to help justify or explain away the conflict between their beliefs or behaviors. This can sometimes involve blaming other people or outside factors."
Personally, I've gone through this. Before I was vegan I was a vegetarian for the environment. When at a family reunion I told my cousin, an agricultural scientist and professor, that I was vegetarian and the reason's why she quite clearly told me that dairy is at least 1/3 of the problem.
This really bothered me. I saw myself as an environmentalist yet I wasn't limiting my environmental impact as much as I would like. So, did I immediately become vegan? Heck no! I continued to eat dairy and eggs, continued to wear wool and leather, continued to do things that I knew she had told me were bad because I wasn't ready to accept reality.
I argued with myself that wool and leather were sustainable (they're not). I argued that she wasn't even an environmentalist so why should I listen to her consequently ignoring her vast knowledge. I even dismissed her statements of fact out of hand because "why should I listen to a conservative about anything".
5 years later my arguments ran out and I went vegan. I could no longer justify my want for dairy and leather when faced with the very real reality that my choices were contributing to an unsustainable system and to the suffering and death of billions of animals and millions of humans.
So, when people like this crop up calling me, a vegan, a person who has given up whole food groups and categories of fashion in favor of the environment, a keyboard warrior I don't sweat it. I know that they're just mad at me because my mere existence causes them discomfort, and that's okay. Either they'll figure out why they're really mad, or they'll find another way to cope and stop attacking internet strangers.
Either way, it doesn't affect my choices or my reality.
