From the OP : 33% of respondents said they would "definitely not" or "probably not" be open to being friends with someone who voted for the opposing party's presidential nomineeI think you have drastically misinterpreted the topic of this thread, and more specifically misread my post.
Either that you you just don't understand the difference between "work" and "play".
You are talking about work. And yes, you need to be able to work with all kinds of people, people with different points of view. You need to treat these people civilly, professionally and work together to achieve your goals.
However this thread was about who you choose to be friends with. And my post that you are replying to specifically states "who you choose to spend time with socially". Do you understand the difference?
Not open to it. You don't need to see that as problematic, and you're welcome to your opinion. I don't share it.
