At the same time though I do identify
with non-political groups with fuzzy boundaries, so why not political groups as well?
One obvious difference is that identifying with non-political groups invites far less controversy. But I think the more fundamental difference is the presence/lack of "central"/"typical" instances/characteristics. At least for the sociopolitical groups I can think of, it's hard for me to pick these out because the groups are so broad with many factions.
@amerika I suppose "politics" is itself a bit fuzzy, so here are the specifics I had in mind:
Sociopolitical groups: Left and right wings (US politics), feminism, men's rights movement, Black Lives Matter
Non-political groups: Fan communities, gender identity (broadly, such as male/female), sexual orientation (again, broadly, such as straight/gay/bi)
Richard Spencer had a great riff on this with his elective and essential identities.
Essential identities are intrinsic, biological, and genetic.
Elective are choices like to be a Star Trek fan.
Politics is somewhere in the middle since it has a clear genetic component.
You make a good point in that politics itself is a bit fuzzy. Most have no idea what Right and Left mean.
@collectedoverspread
Depends on what is meant by politics.
General gut leanings reflect the character of the individual.
