Uhm... I'm completely flattered. WTH is the reasoning behind CSD T1? How did that ever pass community concensus? I can't believe more than a handful of people would agree to that! What on Earth is supposed to be harmful about users proclaiming their view on religious or controversial topics?
Wikipedia is an encyclopedia, not a battleground for social, moral, or religious issues. Userbox templates and user templates group Wikipedians into competing factions. This infrastructure has been used in the past to abuse our decision-making policies by vote-stacking.
The obvious logical conclusion is not that userbox templates are unsuitable for Wikipedia, but that voting is unsuitable for decision-making.
If you really feel it is necessary to proclaim your religion on your userpage, you can do it, but you don't need a template to do so.
If you really feel it is necessary to stop people from proclaiming anything about them (not even specifically religions) using templates, you are free to voice this opinion, but you are not entitled to delete any such templates without community concensus.
