You're not being unreasonable. But you also don't need to "rage quit."
It sounds like the culture is shifting in a direction that doesn't fit with the way you'd like to work. Time to move on, simple as that.

It feels like we are being treated like children and stuff like not being "real" software engineers coming from people who have contributed 0 to the existing code base really angers me (I am a very emotional/passionate person though).
It sounds like the incoming team indeed thinks of itself as superior in some respect. That's a dangerous way to think (regardless of whether race is involved), because they won't be able to learn anything if they've already disregarded the thoughts of those that were around before they showed up.
It also sounds like they are a bit more conservative ("convoluted code review processes... based on jira tickets") and perhaps a bit more authoritarian ("standard that must be followed for EVERYTHING").
Those may or may not be traits that the company needs to succeed at this point in time, but you're certainly not required to accept them or agree with all of them.
And you shouldn't be made to feel like a child if you've built the foundation of the product. It is disrespectful.
So you just need to ask yourself whether its worth it to try to work with them or just move on.
