The thread is about Ron Paul and why (according to the author) he should leave the Republican Party. The articles uses data that implies he may be a racist and antisemitic to bolster that argument.
That implication has nothing to do with partisan politics, nor does it have anything to do with Republican political philosophy. It DOES have to do with what I referred to as the 'seedy underbelly of human existence'. Thus the implication that Ron Paul is more Republican than other candidates can be seen to imply that Republicans by definition are racist and antisemitic.
If you want to leave that implication on the table, then I question your Republican credentials.
Question them all you want. I am a republican. I owe no allegiance or support to the Republican Party beyond the degree to which they share that philosophy. Party names don't mean squat.
