Cat, you're not alone in feeling this way. Believe it or not I go through some of these issues while negotiating between being a Muslim and also being involved in the secular world. I don't claim to be some angel here but I am damn better than some people on Gupistan and elsewhere, who think that they are holier than thou.
I pray 5 times a day but also go out clubbing, parties with friends, work colleagues. I have never had a drop of alcohol while being out but will dance to my favorite beats. I have more friends that are girls but never dated forget kissing or even touching a girl inappropriately. My parents are much more liberal than I am, so dating, drinking or anything else would be no big deal to them, but my imaan stops me from crossing over to the haram side. So yes, I don't just go to work and come home to pray tahjjud, but my rep at the *Islamic *Center has never been questioned. May be I am a biot materialistic, like my suits and cars, but I also give 12% of my gross income in the name of G-d and do 2 nights at the soup kitchen. I am not a hypocrite becuase i work hard, believe only in G-d and his beloved Messenger Muhammad (PBUH), an treat everyone (Muslim or not) with respect and humanity.
I am not going to step back because I am Muslim. EVERY single rule of Islam is rooted in the scientific inquiry, metaphyics, and logic. So it's NOT difficult for me to follow the rules of Islam - it is something that I embrace.
I usually don't get personal here, but reading your note struck a chord. Keep smiling, stay fly :)
Becareful when you say those bolded words. The best of our Shaikhs always said (Maulana Ashraf Ali Thanvi being one of them)- "I am the worst of ALL Muslims"- and they were one of best Muslims, and if they thought that, then well I don't think we have any right to think we're better then anyone else either- even if they do have the holier then thou attitude (and honeslty your whole post sounds"I am holier then thou."). Mashallah, it's great you do all this stuff, but honeslty but please stop with the "I do this, and I do that"- I hate it when some guppies do that to prove there point.
