You realize there are hundreds of millions of Muslims world wide? If you want to take the actions of a fraction of a fraction of a fraction of a percent to base what you think of an entire group of people on. You shouldn't like anyone, religious or not.
There are more than a billion, I think.
The question is, though, not how many of those commit suicide bombings, but how many out of this billion promote freedom of speech and press, democracy, separation of church and state, women rights, tolerance towards other races and religions. 10%? 20%? These are the people I base my opinion on, and my opinion is very bad.
Other than that, the fact there are so many of them doesn't make them just or right.
