No. You simply need to have evidence to support your claims.
Like the Aristotelian axiom say:
"That which is asserted without evidence, can be dismissed without evidence."
Nope, afraid not. I don't make claims without a supporting argument or supporting evidence.
No. I simply pointed out that your post was filled with several "I think", and not one "I know".
You're speaking in very definitive language for someone with little more than an "I think" to contribute to the conversation.
I'm saying your claims have no evidence to support them. If you did, you would present them.
