It is different because it is different. You either see the difference or you do not. There is no point in me trying to logically explain why it is different because as a conservative who may not want to see the difference you won't. I could give you the logic and you may rationalize it away. It is pointless to try to make pigs fly because it frustrates the instructor with the hopelessness of the task and it pisses off the pigs. Actually, of course, it doesn't piss off the pigs, it just brings to the surface how pissed off the pigs already are.
Try to see this only as the use of a existent metaphor with no intention in any way to imply that you are a pig. Similarly, the brain defect term I use is only defective in situations where fear needs to be modulated by logic and reason, not in situations where a more liberal brain may fail to react to an immediate danger and slow the response time fatally by thinking. Panic and strategic analysis each have their places. Thinking for a liberal brain means the rational analysis of context based on scientific understanding. Thinking for a conservative means finding rationalizations to avoid truth that damage the ego. These aren't absolutes but accurate generalities, provided, of course, you can rationally deal with the data that so indicates.
So again, your claims of similarity are, upon analysis of the context, not accurate. I read the analysis the other day when the claim you are making here was made elsewhere and rebutted but I don't now remember where.
Forgive me but I'm a bit jaded with arguing logic on P & N. The central theme of the difference is relative importance of the issues for the different Presidents which refers to the fact that Obamacare is a seminal achievement.
