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.
