I, too would be put off to find someone assumed I was gay. What, am I acting effeminate or something??
I'm not gay, but I don't mind talking or interacting with someone gay - so long as they are at arm's length.
But seeing two guys kissing/getting it on? Revolting. Is it my DNA? My conditioning? I don't know and I don't care.
Slapping a label of 'Homophobia' on that would be wrong, too. Unlike my father's generation,
I don't feel gay men should have the shit kicked out of them merely for being gay.
No, that's... pretty much homophobia, and it's not wrong to say it is. As others have noted, it doesn't have to be violent or dangerous to be homophobic. I am curious about two things: do you think that there aren't gay people on this board that might read this and feel a little put off (good to know we only disgust you and you don't think we should be beaten for that), and secondly, do you feel the same way about gay women? Lots of people are all right with two pretty girls kissing, but not so much with two men, pretty or not. Also, you don't need to keep the gays at arm's length. Everyone knows that the gay is only transmitted sexually.
As for the comic, Marten seems pretty fine with gay men - I don't consider him homophobic. Especially after interacting with his father, and his support of his dad's desire for partnership, I don't think that he'd necessarily be offended that Padma thought he was gay with Steve. Rather, I think he's just frustrated that Steve's monopolizing the conversation and seeming like he's not disclosing his relationship status (that might be concern for Cosette, or it might be jealousy of Padma's attention, both, or some other reason). Steve, on the other hand, I'm not exactly sure. He hasn't shown any real reasoning one way or the other, from what I can recall (and I may be mistaken!).
And the poster who said that the homophobia is projected, yes, it pretty much is. Most of the responses have been about what other commenters on this board have said, but I think it's relevant to the comic itself. Jacques has clearly made an effort to make realistic characters of many sexual orientations, and tried to be sensitive to them. How the readers interpret that, and how people of those sexual orientations feel about the representation matter. Gay people and homophobia are pretty common jokes, and they can either reinforce negative ideas about gay people and the like, or they can sort of undermine the humor in degrading other people. I feel that this situation, we aren't supposed to laugh at the idea that Marten and Steve are gay, but rather that Padma keeps saying the wrong thing and that Steve and Marten do sometimes act like an old married couple.
