maybe he thinks you are allowed online if it’s “l’toeles” and he considers trying to get people to not be zionist to be a “toeles”.
not saying that I agree; I just don’t think that one should assume he is a troll or conclude that he should not be on the internet just because he is anti-zionist. One can argue that none of should be online since to some degree there is a “stira” between anyone being on the internet and being Frum, but we all have reasons why we decided that it’s okay (rightly or wrongly).
