Salaam 'alaikum I didn't mean hardcore as an insult. I simply meant that these brothers and sisters are very committed to their view of Islam, wether its from newness to the deen or from being firmly convinced from in-depth study or some other reason. Its much the same as being called a "hardcore" hanafi. It just means that they're strict in adhering to their way of approaching Islam. Again, I said what I did because its true, not to pass judgement. In fact a brother I know who attends that masjid was instrumental in my coming to Islam and in my development as a Muslim early on.
