I feel like difference in opinion, even in fundamental assumptions about life, shouldn't ruin peoples ability to enjoy a beer together and/or have a friendly discussion
As long as the attacks don't become personal, we should be fine.
In this regard, I have certain relatives who really love to talk politics with me, and we really have a lot of disagreements about the roll of government and various applications of libertarianism... I have a couple of relatives who do NOT talk with each other b/c they do NOT like the way conversations devolve, and frequently, I strive NOT to take the conversation too much into the personal.. but it is all a matter of perspective, and sometimes, each of us may go a little too far.. and have to pull back.
Further, sometimes I get the feeling as if couple of my relatives are trapping me into some kind of lunch or breakfast situation, and then ganging up on me, yet ultimately, we generally are friendly enough about our whole exploration of these issues. A frequent comment that I make is: "so you guys have been working (studying) all week in order to figure out some ways to attack my world views with your comments." One time, my grandma, who is in her late 80s was sitting at the table for breakfast with my sister and my uncle going at me, and pretty soon I said, so you want to throw grandma under the bus in order to achieve dismantling of social security.. etc... etc. .. etc... Of course, they denied such motives, and we all got a kind of laugh about some of these attempts to apply real world situations to our theories.
Sometimes, if we are going too far in our conversations, we would just revert to talking about some less controversial topic, and in our case, we may be able to revert to talking about how we expect bitcoin prices to go through the roof and when we expect that to happen.
