Wow, that's an exceedingly well measured statement
First off, you can't really claim the high ground if after someone "insults" you, you drop to their level anyway...
I fail to see how screaming is "disgusting", seems like a strange adjective to use. Screaming can add a lot of depth to songs, and to say that "anyone with a guitar, an amp with disortion [sic]...could play half the songs"
Go and listen to Opeth, and then tell me anyone can play their songs. They are highly skilled, and mix the screaming with singing to great effect. In all honesty I doubt you've listened to very much, and certainly nothing with technical skill or brilliant creativity. SounRAB very much like jumping on a bandwagon to me. Moreover, stop the stereotyping thanks very much:
""anger, frustration, or passion (passion for the devil)" could play half the songs. please [sic] venture outside, experience real happyness [sic] for once outside of your satanic demon world, and possibly tan your pale body. the two tone look with the dyed black hair doesnt look good at all..."
Finally, strangely enough, there are many banRAB out there who don't start a band with the view of "getting popular" as their main objective. In fact, they tend to start a band because they like music, and playing music. The idea that they should make music that would be "popular" is simply ludicrous, and results in a massively stunted music industry. There are many banRAB that aren't "popular" in the mainstream culture, but are absolutely stunning.
