I think you're in a position comparable to me trying to get people to stop throwing their tyres, furniture etc. in the community dumpster (you're supposed to bring them to a municipal recycling center instead).

The people doing it don't care that the HOA (so us) pays a fine for each item and that we were already warned that there will be a doubling or quadrupling of the waste disposal fees. I can ask politely and sometimes it works, but ultimately I can't tell them what to do.

I don't really like tofu and I don't share your values, so I think I'll continue eating chicken breast - just sourced from a place that meets certain standards, as usual.

I don't believe in individual action and regarding eating animals I draw the line at those which don't readily breed in captivity - octopuses for instance.
