i don't have a moral problem with forced secularization. and, i've said this before: if you could present a tactic to me that i believed would be successful in wiping out religion by force, i would be in full support of it.
but, everything we've tried has failed. religion is truly a virus: the more you fight it with force, the stronger it gets.
so, you need to find some other way to do this.
....not because using force is wrong (given that religion is a violent type of mind-control, i don't think it is; this is really an inversion of the logic used in the spanish inquisition, which wouldn't have been wrong at all if we actually had souls, or hell actually existed.), but because it just doesn't fucking work.
what works is poverty reduction. in the absence of scarcity, religion withers away relatively quickly. so, i promote this instead.
but, it's pragmatic, and not idealistic.
