Unpopular opinion: I'm not sure "unity" is something we should aspire to as such. We should aspire to be inclusive and free from hate. But within that, I aspire to a kaleidoscope of contexts, religions, and POVs with a representative democratic structure that serves us all.
Or to put it another way: the idea that there should be a prevailing patriotism or one dominant religion is undemocratic to the point of being regimented. Diversity will set us free.
