A person that is open to learning new facts & ideas is worth their salt. I have new respect for ML.
That is why I hate using the term liberal for modern day leftists, because liberal implies a willingness to seek out the truth. It is also why I call myself a liberal to a degree. I am always willing to listen to other arguments. The only exception is when it has been proven on more than one occasion as to not being an idea to be pondered further. Due to the fact it have been proven false.
