Would you defend a friend who makes racist slurs on a message board? It says something about the company you keep. If a friend of mine made comments like what sharma made I'd give him a serious talking to.
Dude, it's only a message board - let's not take "racist slurs" here so seroiusly

If I complained every time I saw a discriminatory post against Muslims or Arabs or Browns I would have no time to post about Nasser let alone anything else

Sharma is now on a jihad against CJ because CJ doesnt conform (in his eyes) as to what a "good" muslim is. What is this crap about trying to be white that CJ is supposed to be having?
I didn't follow the CJ and Sharma debate too closely, but I didn't see anywhere Sharma initiating comments against CJ for not being a "good Muslim." If any such comments were made by Sharma, they were probably in response to CJ questioning Nasser's faith.
Is Nasser also trying to be white since he drinks, takes drugs and has a dog ( i thought muslims dont like dogs)?
Only white people drink, take bodybuilding drugs or have dogs?

Newsflash - there are 1.5 billion Muslims and among them probably only 200 million practice or would be considered "devout." How many Christians have pre-marital sex? Probably 99% of them?
To answer your question about Muslims "not liking" dogs - Islam actually promotes kindness to animals. Treating animals nicely, feeding them, etc. is encouraged while mistreating them is considered a sin. As for keeping dogs as pets, they are considered to be more difficult to keep clean (in general) than other pets like cats, for example, so as a result it's recommend not to keep them in your home as pets.
