Here's the thing:
Our government(s) are "supposedly" secular ones, and in keeping to neutrality, it has granted people the freedom of religion.
The freedom of religion means that you can belong to any religious sect you choose to, that you shouldn't be coerced into practicing a religion you do not want. This is what allows people to convert from one religion to the other.
The freedom of religion however has become warped and garnered the meaning, that it affords us freedom from criticism. This isn't true, I am not estopped from pointing out the inconsistencies of your religion because it is your religion, You have the freedom of religion, I have the freedom of speech. An attack on the doctrines of your religion/faith isn't an attack on you, well, unless you want it to be.
Buy this hasn't been true for the world in general and Nigeria in particular. It is interesting that when people speak out against religion, the usual response is usually a plea for the speaker to turn the other way - and leave people to their beliefs - or an angry retort. It would appear that the freedom of speech or criticism against religions isn't really guaranteed by the laws of the land but by the religions themselves. Can you imagine people making posts about the pitfalls of Christianity, comedians making jokes with priests? That's mostly because that already happens, And that's alright.
A religion that seems to have conquered the world in this aspect is Islam. Other religions expect to enjoy some level of special treatment and safety from attack, but no religion matches Islam in the way it usually responds to criticism. This is why it is hard to imagine people making posts or jokes about Islam. Remember that time a Danish newspaper reportedly carried a caricature of the prophet Muhammad? Remember the outcry and the ensuing drama that followed? The countless lives that we lost?
No, the problem isn't the people that practice this religion. The problem is that religion tries to keep itself alive, and it does so by stifling critics.
