that they’re largely city-dwellers

Since cities are densely populated then most people are city-dwellers, including leftists and workers. If hunting is working class and most of the working class lives in the city...you see how your point breaks down. You can't really pin being hunting-adverse on being in the city. People live in the city and then go on hunting trips. Why do you think Cabellas and Bass Pro exist? Being an urban or suburban hunter is pretty common.
