I think the above comment was kind of blowing the comic out of proportion—I mean it’s a 4 panel comic it’s obviously not going to be able to give great nuance but I think it’s easy to read it as “proper” queerbaiting.
Anyway, the Wikipedia page has a good list of examples if you’re interested in mainstream examples.
Ones that stick out off the top of my head I’ve personally watched were Sherlock, and Teen Wolf and Rizzoli & Isles to a lesser extent.
