In Animal Farm, what are some reasons why Snowball would be considered dangerous?

I find that linking the Animal Farm
characters to their Russian Revolution counterparts helps me to think through
why they do what they do.

Snowball represents Leon Trotsky.
He was a celebrated military mind, and he instituted many committees. This is a
dangerous place when the committees don't necessarily achieve
anything.

Snowball followed in these footsteps. He tried to
institute these committees: re-education, planning and development, and production. What
has made that dangerous for Snowball is that he spent all this time thinking and for
what? Working with incompetent animals? This is dangerous for him, but it is also
dangerous to another authority figure because it shows that he can think and
plan.
