As a lifelong runner, when I saw this commercial, I simply thought, "oh, this guy is a just one of those jogger types, and not a serious runner". Somehow someone in the gay community was "looking" hard for something to complain about, and put a big SPIN on this advertisement, making it seem like it was poking fun at gays. Football is about the most "macho type" sport on earth; why don't they make some claim that "football makes fun of gays." This commercial was nothing short of just funny.
I sent a note on the internet to tell Mars that I'm going to boycott their products, because like so many companies these days, they are lying down and playing door-mat to any group that whimpers about somehow being offended.
Here is the link where you can tell Mars what you think about playing "door-mat" to these groups.
