Really?


Say, you don't know what python is and have no use for it and therefore 
want to remove it to slim down the footprint of your installation:

# yum remove python
...
Error: Trying to remove "yum", which is protected


Similarly, a new-comer can be tempted to remove this meaningless package 
called "bash":
# yum remove bash
..
Error: Trying to remove "systemd", which is protected
Error: Trying to remove "yum", which is protected

I disagee. In general, people do not know what to answer, because they 
are unable to estimate the impact of what "yes" may have.

This not only applies to new-comers, but to everybody.
It's just that Linux professionals and Linux nerds may have a coarse 
imagination that removing something could have disasterous consequence, 
but in general, they also frequently hit their limits when being 
confronted with "OK to remove foobar?".
