I don't see how this would matter though. In a dating app, someone who refuses to date zionists will notice if pro-zionism is on their profile and not match with them or even block them. If there is no mentioned zionism on the rightwinger's profile and the rightwinger is trying to trick people into dating them whether the anti-zionist is able to post "No Zionists" on their profile is immaterial, the rightwinger will try to match with them regardless.
