Well, certainly. But we also assume that a person in a group shares opinions with others in that same group. That is how we are able to talk about groups. Like assuming that American conservatives are against gay marriage. Or that feminists are for equal-pay. Or that socialists are for socialized medicine.
Unless it's a group with some sort of hierarchy in which it's expected there's some sort of representative/spokesperson, that assumption isn't reasonable. I'll give you that in case of groups like political parties, religious sects, unions, fan clubs, inhabitants of an area of administration, yes, it's reasonable to assume that whoever is the "leader" or "spokesperson" for such a group, speaks for the people in that group, unless the people state disagreement. Such groups tend to be "opt-in".
But there is no leader/spokesperson for "men". There's no leader/spokesperson for "feminism" (at least not that I know of). There's no leader/spokesperson for "gamers". There's no leader/spokesperson for an entire ethnicity, an entire gender, or any other kind of demographic that's only a demographic because its members share one particular attribute, be it skin color, what they have in their 23rd chromosome pairs, or what kind of entertainment that enjoy.
So yes, if I'm a Catholic, it's a reasonable assumption that the Pope speaks for me, unless I state otherwise. If I'm a member of a political party, it's a reasonable assumption that its leader speaks for me, unless I state otherwise.
But it is
not reasonable to assume that any particular white guy speaks for me just because I happen to be a white guy too. I did not choose to be a member of this demographic, I just happen to be one. There is no hierarchy I am beholden to, and nobody who speaks for me in it.
