If you can't explain why your idea is good to a junior engineer, voting is the lead of your problem. If you mistrust half your team as a rule, how can you trust anything to get done well?
It's hard to explain to junior engineers why chasing fads is a bad idea. Why boring technology is often the best choice. That's only something that most people figure out with experience.
Seniors often don’t like doing new things for the simple reason that they already know how to do things a different way and they don’t feel like learning something new.
and juniors like to make mistakes because that's how they turn into seniors.
The point is, and will continue to be, that a senior's opinion should be heeded or you disallow them from steering the ship away from the glacier that they know is there.
You can always justify everything with a reason. If your goal is to justify, then great, you did that. If your goal is to be effective, you need to stop trying to justify.
