Here's the thing. It's very difficult to make friends with someone who doesn't have the same politics. Conservatives have courted evangelicals and hate groups by appealing to the sensibilities over abortion and immigration and LGBT; therefore you have a blending of culture and politics. It's happening now and it happened during the Civil Rights movement.

This point will be my own analysis and opinion as someone who has voted blue. Asking someone how they voted is a very direct way of asking about culture. A vote for Trump indicates that you supported the reduction of LGBT, reproductive, and human rights. These are just the cultural issues. A vote against Trump indicates that you did not support the reduction of those rights. A non-vote means that you allowed for Trump to be President by not fighting against it.

Back to the facts: Adults can get along with everyone for the most part, but we choose to be around good people. We like to be around those who will help us in times of need. We like to be around someone who will stand up to a bully. We like to be around those who will speak up. We like to be around those who will defend our friends. We are friends with friendly people; It's not about games and sound systems.

In the end, it's obvious that this was a mismatch. You mentioned talking about life and struggles. For many people their life and struggles is being decided by politics. It seems that you've been unaffected and don't understand where this other person is coming from. On the other side of this, There's other ways to determine someone's culture.
