Just because something is denoted as "queer" doesn't automatically equate with it being gay.
If you were a member of a minority community, constantly fighting for rights and freedoms granted to others, all the while taking abuse for simply being who you are, then it is not hard to see why people become sensitive to such things. In this case, with Jeremy Clarkson's reputation, I don't think it could be construed as anything else.
But to be honest, with the general undercurrent of homphobia on this forum, there are not many people on here who'd understand/care what the fuss is about.
