you're not discriminating against lifestyles when you judge all jews for what the israeli government does, how are american jews responsible for that for example, or jews who live in israel and are against the government and its actions? or do you claim there are no such people?
The point is that that's not why (or when) Jews are really judged but bigots will use whatever they can.
and it's not a choice to be jewish, you are born that way. secular or no, you're always gonna be a jew. that's what makes it a race.
"Generally, in modern secular usage, Jews include three groups: people who were born to a Jewish family regardless of whether or not they follow the religion, those who have some Jewish ancestral background or lineage (sometimes including those who do not have strictly matrilineal descent), and
people without any Jewish ancestral background or lineage who have formally converted to Judaism and therefore are followers of the religion."
