Having been part running of three +1000 members computer clubs with a weekly attendance of about 10-150. I would rather say that if you are not political you do not have a club.
One of the standard by laws for clubs here is "not bound to political party", i.e we had a few extreme right wing people and many left wing and a great mass of moderate.
GNU GPL is political, every choice you do in computers have a political component. You choose if you allow piracy, black hats, surveillance, alcohol, meat, veganism etc. These are political decisions that will effect the feel of your club, even if you actively do not care about a decision.
The important part is that the club needs to survive and it only does that if you manage to find new people who wants do stuff, and put partisanship aside.
