dont fear them, treat them as brothers inshAllah, they are your brothers. Many of them are strong in their imaan alhamdulillah and have love for islam which is not the case for many muslims today so the strong shoudl work together to help the 99% who are drinking and clubbing and committing haraam ratehr than the 1% who are actually practising fighting each other. Dont get into debates with them, just practice your way and let them practice their way inshAllah
