Is only the combination of drafting and going into another country that is unacceptable?

Forced draft alone is bad, ordering soldiers to invade another country it's even worst.

Is Ukraine even using conscripts on that front?

Good question, are they? I think more people should be concerned about it especially these who are supporting their own government in sending weapons to the government of ukraine.

The goal of the invasion into Russia (in my estimation) is to take territory to trade back to Russia in exchange for parts of Ukraine that Russia has captured. Do you think that’s not okay? Why?

This isn't a video game, what we are talking about is potentially forced conscript being ordered to invade russia and dying there a miserable way so that governments can trade pieces of land.
