they are great conversations about why people are so annoyed by vegans and most of the time it’s not because vegans are harassing or pushing their agenda, it’s more a question of how we perceive ourself when comparing ourself to others.
it’s due to cognitive dissonance.
I totally understand your point of view and think that your perception is valid. If you try to analyse why you find them preachy and judgemental it could be interesting.
For example would find them so annoying if you agree with them? Is it the discourse that annoys you or the person? Is it your belief system being challenged that annoys you or the facts that are being stated?
It’s always intersting to understand why we feel that way when we are challenged, and veganism is one of a few topic that can create what we called in psychology reactance, an interesting topic.
Veganism is really different than religion tho, cause it is totally backed by science (regarding food production, waste issue, C02 and sentientism) and a logic construct.
