At threat of sounding like the classic "whatever they do on their bedroom with consenting adults is none of my business" libshit, I really don't give a fuck what Dev is attracted to. That said, the "none of my business" part is a huge aspect that Dev refuses to actually take part in.
I don't think anyone on the left would see him as a weird chaser if he could just shut up about it, and no one on the right would see him as a weird wishful poly degenerate if he could just keep it to himself.
This actually was my first reason to distance myself from Dev's content. The way he talked to his tranny mod during seethes was very gross and put me off of watching anything live from him far before his content took a dip
