Buddhism and Islam are not threatening to Nepal. Islam may be a problem in Afganistan, but not in nepal. I have not heard anyone converting to buddhism or islam in nepal. the only problem i've seen is from the Christian missonaries. i saw churches being built in remotest villages of nepal. so the real threat to everyone else in secular nepal are the Christian missonaries. this is the reality. accepting it or not accepting it is your choice. majority of the poorest people in nepal are the janajatis and the dalits (truth is always bitter). so now they will be the major targets of the christian missonaries. hence, in nepal now the janjati culture of the backward janjatis will be replaced by christianity. there will be no chepang, bote, sattar, musahar etc type of cultures now. because now converting your religion by any means will be legal now. i have already seen many converts like martina uranw, david praja etc. it is only a matter of time now. so just wait for 10 more years.
