First thing first, 1. i'm a muslim and I think organisations like SIMI should be banned permanently and leaders should be prosecuted. Also, other muslim organisations that speak on behalf of all the indian muslims should be banned, including the ones in UP who negotiate the ram-mandir-mosque issue. I think muslims should gift the land and in return hindus should build a mosque somewhere. This will solve half the problems.
2. With regards to muslims destroying mayan culture? Where did you pick up this facts from? It was the spanish missionary under their king's leadership that killed mayans. Muslims went nowhere close to south america.
