At least it's for a Hapoel team. I don't know how much you can trust Wikipedia, but as can be seen by the hammer and sickle in their logo their fans are usually leftists or at least socdems and used to somewhat commonly wave flags of Karl Marx and Che Guevara, at least in a few football matches of theirs that I saw.

They're also the biggest rival of Beitar Jerusalem which is the Israeli far-right club that even forbids Arabs of playing for them
