I'm genuinely curious. That's it. You've asserted that capitalism "is no longer a viable economic system", but won't talk about why you think that.
Do I lean to the right? Of course. You consider me a lost cause and you don't even know me. If you are correct about which is the better system and why, I would think you would want persuade others, but if you choose not to, no big deal. I'll probably still ask why whenever I see an assertion made. In any case, what I generally see is that people are quick to toss around assertions without backup and badmouth anyone who doesn't agree with them. If you've made your case in another thread, link it. I'd be interested.
