The number one question I get asked, even more then if I wear my hijab in the shower (really!), is phrased in two different ways :"So what made you convert to Islam? (this is how non-Muslims phrase it)and "What was it that made you decide to convert to Islam (Muslim phrasing).
Whenever I get asked this question, it is a massive struggle not to emit an outward groan to match my inward one. As I get asked this All. The. Time.
For Muslims, they are genuinely happy with me. For some there is also the political implication of a westerner rejecting that way of life. This is because they think Western life is all wine, orgies and wearing mini skirts. This is no more true then the idea that the Middle East is a haven of correct Islamic living.
From non-Muslims, the automatic assumption will be that I've converted because I married a Muslim, like there could be no other reason why anyone would want to "do that to herself" (that's what one of my Indian Christian colleagues demanded to know when she saw me in hijab). Then, I always get treated to the religious background of the person asking the question. Which I didn't actually ask them about, because I'm not interested. People's religious beliefs are their own business.
Which, for me is the crux of the matter. No one takes the decision to convert lightly, it is a heavy decision, with a massive impact both pre and post conversion. I won't tell people this, because often I don't know them well, yet this is the first question they've asked after "What is your name?"
This means, that people are often not satisfied when I've told them, saying there must be more to it then that. Well, I make no apologies if my story doesn't meet their dramatic high standards. I've told as much as I feel comfortable with.
For those who crave other people's drama, I have to disappoint you by saying most conversion stories often follow a similar pattern: Person meets Muslim in varous capacity (work, school e.t.c), talks to person about Islam, reads about Islam/meets other Muslims, is surprised that Islam is not what they thought it was, becomes convinced by Islam, converts.
So next time you meet a convert/revert, resist that overwhelming temptation to ask them why they converted. Remember that they get asked that question on an almost daily basis. Finding something interesting does not actually make it any of your business.
If they want you to know, they will tell you.
