I think the point is that making the trains run on time is what they call ''a neutral thing'' and wanting religion out of politics and the public forum ''a morally questionable thing''.
Wrong - wanting the state to be neutral toward religion, neither favouring nor discriminating against people whether or not they are religious or of any particular religion wouldn't seem to me to be in any way 'morally questionable'. Quite the reverse.
Would you consider it to be 'morally questionable' for a state to act in a manner than neither favours nor discriminates against people on the basis of their race, or their gender? Probably not, so why do you do so on the basis of their religion or lack thereof.
Banning religion on the other hand is certainly 'morally questionable' but secularism isn't about banning religion - indeed the notions of secularism and banning religion are in fact oxymoronic.
