Don't argue with me. Don't fight me on this.

The second sentence is correct. Also I would say "suburban whites HAVE lived" since it's an continuous/ongoing condition.

"If I find it interesting, I will click the subscribe button to get notifications for updates."

Cut off in a haphazard or aggressive way. So in this context I would picture the haircut being really uneven and maybe messy- looking. But in a stylish/punk way I guess since the narrator sounds happy about it.

I would say neither. "I suggested that we could leave earlier" or "I suggested we leave earlier"

The definitions are pretty similar but the common usage is a bit different. Weird is used in a really wide variety of situations to describe people or things that one deems unusual/strange/creepy, whereas in normal conversation, uncanny is almost exclusively used when people or situations bear a striking and unsettling resemblance to each other. Ex 1 "That guy keeps looking at us, it's so weird." Ex 2 "Hey that guy over there looks EXACTLY like Jimmy...it's uncanny!" You can use weird in example 2 and that would be fine, but to native speakers it might sound strange (or weird!) if you use uncanny in example 1.

Getting worked up implies that the person is upset or aggravated. Being determined just means that you are very committed to seeing something through, not necessarily that you are upset.

I think satisfied can often mean the minimum requirements have been met, whereas content or contented mean a higher level of satisfaction. Content is usually used in a more general sense and contented used in reference to a specific action or outcome, though content can also be used in those cases.
