Differences of opinion are the spice of life. And we do have our fair share here on RR. BTW, katydid I am not a liberal. Liberals practice safe logic. I would rather push the envelope.
I believe that when one doesn't have facts and a solid theoretical backing for one's arguments, then the arguments are most likely flawed from the get go. Anyone can have ANY opinion, many of them baseless (for example, Obama was born in Kenya) and it is that aspect of many conservative (for want of a better word) arguments that makes them the butt of jokes.
Denying climate change in the face of overwhelming evidence is another.
Denying evolution in the face of overwhelming evidence is another.
Denying economic inequality in the face of overwhelming evidence is another.
Denying racism in the face of overwhelming evidence is another.
So, my beef with most of the "conventional" political parties is that their arguments are basically flawed (and based on some corporate agenda instead of the actual needs of the people) and their actions do not correspond to their promises.
