No, Stinkcat. Expanding government programs or starting new ones does not in itself constitute being a socialist. Increasing a tax on its own does not make someone a socialist. What I’m trying to get you to grasp is that what matters is the larger ideology - an astute socialist might call for privatizing something - but that does not mean he / she has abandoned his/her ideology - two steps forward, one step back, etc.
Also, regarding your 2nd point, just because a politician cannot reverse or reform an entrenched program like SS or Medicare, and so does not get up and rant for their abolition, does not mean they are “socialist” as you wrongly state. But we have discussed this before and we will have to agree to disagree.
