A truism, and it doesn't just apply to Texans.
I would say people are becoming more and more alarmed at the level of Muslim penetration in the "Western" world, in general. They are now beginning to hold there own "courts" of a sort, in England.
Muslim societies are QUITE different from ours here - that cannot be denied; and Muslims don't assimilate into ours like previous immigrants. Seeing the aforementioned happenings in England, and the riots in France - coupled with the extreme regimes depicted on the news, trepidation is, frankly, understandable. Education and familiarity are probably in order, and will most likely help the situation. BUT, as long as terrorists all come from the ranks of "Muslims", there WILL be tension. Mormon temples, btw, are treated in similar ways, btw.
