I always saw the Vulcans as Republicans, in all honesty.
They are aggressively xenophobic and use 'logic' as an excuse to berate, bash, ignore, and forget anything that they don't like. They claim to be bowing to ideals set by their predecessors but their predecessor would likely be rolling in their grave at what they've been doing. They don't make any real advancement or go further, they're happy to stay exactly where they're at with the status quo. They abhor anything that's different and see giving any sort of space to that difference as a gracious gift to be given and one that the different thing better be grateful for. They lord themselves high and mighty above everyone else but routinely miss the big picture and end up putting themselves into positions of failure due to it. They put far too much into what are mostly superstitious and religious beliefs and those beliefs often impact everyone. When they have a child with someone who isn't part of their group, they try to raise the child in such a way that the child is permanently torn and confused. When teenagers are confused, frightened and upset instead of allowing them to embrace these feelings and figure out how to control them, they instead root out all compassion and hints of emotion to further what they think is the best.
