'Repetitive and relentless promotion can become tedious, but I feel virtuous doing it ...'
YOU may feel virtuous, but almost everybody else feels you are a selfish ******. 'Repetitive and relentless' doesn't even come close - what you do is hugely insulting. You do not even do people the common courtesy of responding to their comments, you just carry on posting the same old propaganda over and over again. You actively drive away those who might initially have some sympathy for your position. Consequently you are doing your cause far more harm than good. I can only conclude that you don't actually care about the plastic bag issue at all - your motive is obviously pure and unadulterated HUBRIS.
