"you'll need to come out with more compelling evidence that what you've presented."
The comment from System about which you are complaining mentioned the IRA. Perhaps you have heard of them? A bunch of Catholic terrorists funded by donations from US citizens, who tried to blow up various UK prime minister on several occasions, who made many dozens of attacks against mainland targets and thousands of attacks in Ireland (1,300 explosions in one year alone). The total fatalities attributed to the IRA are estimated to be over 1,700. Of course, countless terrorist atrocities were also committed by their opponents, also with depressingly high numbers of fatalities, but strangely, they weren't Muslims either. Until quite recently, having an Irish accent in Great Britain was sufficient for you to be treated with suspicion.
If you are talking about suicide bombers, it might be worth noting that the group usually attributed with committing the most suicide bomb attacks over the past few years is a bunch of Maoists (the Tamil Tigers), and surprise surprise, they are atheists (and hence not Muslims), but of course the country in which their attacks are mounted is usually counted as being in the "third-world", and does not have any oil, so you might not have heard of them either, unless you are a rational, intelligent human, who has even remotely paid attention over the course of the last 25 years...
There are many other examples from around the world, even excluding state sponsored terrorism, but perhaps just these two examples are enough to convince many rational people that something more than 1% of terrorist acts in recent years have been committed by people who are not of the Muslim persuasion. Interestingly, there are some figures that suggest the number of terrorist attacks around the world has been in decline pretty much continuously since around 1967, but for some reason you don't often hear government officials referring to that kind of information very often, can't think why.
"i dont think you really thought out your statement before you made it, because, any rational, intelligent human, who has even remotely paid attention over the course of the last 25 years realizes that 99% of all terrorist acts around the world are committed by islamic extremists."
I love the self-referential humour!
