I think it's very easy to try to "lump" people into particular boxes because of their politics, beliefs and views. I'm probably slightly guilty of that (though for the most part it's tongue in cheek as to what I think about DM readers!) I was brought up by parents who were, at the time, staunch Tories, adored Thatcher and though striking miners were scumbags (Thankfully they've mellowed hugely!)
Equally, working in retail selling newspapers, you get a good measure of readership, demographic AND the comments & conversations which take place in the brief moments of a sale. So my comments aren't unfounded. But to also suggest that anyone who is deemed "left wing" isn't scared of terrorism, being harassed by large groups of people or scared of being assaulted is foolish. I don't like big crowds or gangs of people.. If I'm on the Tube my brain will, on occasions, go into overdrive and think all manner of awful scenarios. I'm fully aware of the fact that there people out there who want to cause others harm. The difference is, I try my best not to let this interfere with my politics. It is entirely possible to have reasoned debate without blaming an entire faith/race/culture for the misdemeanours of a few and allowing that to hinder our rational thinking.
