Is there huge muslim community in that area?

I am planing to move to carrolton. But i have heard there are more shiya and kods in the school even dont talk to others just shyas

yes quite a few

I am not sure what do you mean by huge but there are lot of mosques around in dfw and yes this is a big mosque too

Yes! A little smaller compared to Richardson and Plano but big indeed :)

I the DFW area overall yes. Not sure about the area around the masjid.
