Non sequitur to the issue of people wanting religion out of politics.
A totally biased misrepresentation of secularism - secularism is about formal structures, in no way does secularism prevent religious people being involved in politics, nor using their religious beliefs to inform their political opinions. What is does object to is a state religion, religions (and religious people) being given special privileges due to their religion. It objects to people being placed in positions of political power specifically due to their office within a religious organisation (e.g. our current situation with Bishops in the HofLs), it objects to state funding of religions.
Does secularism prevent a religious person attaining high political office and power - of course not.
