I have a few problems with this question.
First of all, a true “anti-religious” person is also against Judaism. They are anti-religious, so they are against all religions. Secondly, few people I know are “anti-religious”. Thirdly, what part of a religion is going to be attacked? Is someone who is opposed to religion in general just going to start attacking religion out of the blue? They’re probably going to need to be provoked first.
When I think of comparing Christianity, Judaism, and Islam, I treat Judaism a little bit differently. As people have said, Judaism doesn’t seem to impose itself on others as much as Christianity and Islam do. Think about this: how many Jewish extremists have you heard of? We all know of Christian extremists like Pat Robertson, Jerry Falwell, Fred Phelps, etc. We all know of Muslim extremists like Al Qaeda, Osama Bin Laden, etc. But Jewish extremists? I’m having trouble naming any at all.
Not to mention there are around 2 billion Christians, 1.6 billion Muslims, and 13 million Jews. Of the adherents of the Abrahamic religions, about 55% are Christian, 43% are Muslim, and around 0.4% are Jewish. There are just far fewer Jews to begin with, so much less of a chance of encountering them in the first place and much less of a chance of being provoked by them.
