I can appreciate that your point of view is different. We're all entitled to our own opinions. But no one thinks fish tanks are more important than starving children or being in a war.
In fact, I'm sure no one on sports, art, gaming, decorating or cooking forums thinks their hobbies are more important. But that has zero to do with this thread. And believe it or not, people discussing how to take care of fish neither causes wars nor starvation, and if we were to stop discussing fish it will not end wars or starvation.
So your point is moot.
And although our lives may not meet up to your standards, we all have a life. But thanks for your heart felt concern.
