Well, you are certainly entitled to all those opinions.
My point would simply be that fear and hatred are also valid emotions and opinions.
...and the Tsarnaev brothers actually took their feeling to a different level, actually bombing people, which I never even hypothetically advocated.
The word "fear" has many connotations. It is not necessarily "trembling fear that he is going to harm you", but can also include "the fear that certain people are corrupting the moral fabric of society". Is that not a valid fear ?
For example, referring back to the Bill Nye Science Guy "Science of Sexuality" video. If you had a pre-pubescent son or daughter, would it be valid to "fear" that our society is now filled with people actually advocate "trying a little sucking...you know...just to see if you like it" under the guise of "science", or maybe a little group orgy, because 'why limit it to one " How do your kids know they won't enjoy a little "butt stuff" unless they try ? It's SCIENCE, DAMMITT!
