I never asked anyone to stop eating meat or even reduce it. I only tried (very politely, because I know this is a sensitive topic) to point out the effects of overfishing etc and in my experience, people don't want to hear it. In many cases, they are fully aware of the effects of meat/dairy industry, they still don't want to give up meat. This I understand, I struggled to give up coffee for many many years.
On the question of reducing subsidies for the meat industry - are you aware how powerful the meat industry is? Even the almighty Oprah at the height of her fame and reach couldn't do anything, got sued by the beef industry. There are a few states that have ag-gag laws, do you really think there is political will to repeal these?
In my town, a single mango costs $3.49. Sure it would be nice to subsidize fruits and veggies, but animal industry lobbying is way more powerful than mango/watermelon lobbying.
I appreciate your positivity, I suppose our experience on this issue has just been polar opposite.
