Yeah, actually, that wouldn't bother me at all. But it would bother the exact same people as were offended here because of the implicit assumption that black guys are larger than white guys (which, statistically, they are - a fact that, when it arises, elicits desperate, indignant howling to the contrary on this site). In fact, I'd suggest you prepare yourself for some rough treatment, ganja, for even thinking of that analogy. It reveals unacceptable thought - you horrible person, you. Maybe everyone will cut you a break because you're 19 and have presumably been crippled by your schooling (or more appropriately, indoctrination).
You can take offense if you want, but when people rise en masse to shove a guy down over the slightest, most innocuous comment, well, I take offense to THAT, especially when they've formed a monolithic psychological disposition that they deploy instead of thought in order to advance their worldview.
Toughen up and use your head. You don't have to like the guy's comment, and you can "take offense," but there's absolutely no reason for the lemmings to line up and spew forth their carbon-copy condemnation.
