Just by observation you'll see that criticism of Christianity is fairly common and books/videos/lectures/blogs etc. on that mattar are easily accesible. In short, you are clearly wrong on that one.When it comes to Judaism, it's a bit different because it has much, much less adherents, but, again, there is no-one stopping you from criticising it.
^ Of course we are allowed to with freedom of speech, but as soon as you open your mouth to criticize ridiculous religious superstitions you'll be accused of religious intolerance or will be called a bigot. No, if an idea has no basis in reality, then it very well should be criticized so that it spreads no further. This is more attributable to social interaction. It's "impolite" to criticize someone's beliefs. Sure, people talk shit about religion on the internet all the time, but you won't have very many friends in real life if you criticize deeply-felt convictions of people in person.
Haven't you ever heard the cliche "it's impolite to talk about politics or religion"? (Mind control propaganda in my opinion.)
