The problem with this topic and every topic related is that people think that Stalin=Communist.
Communism is a good system if done right. Stalin was a paranoid maniac who had the power.
That doesn't make the whole system bad.
Is every sort of energy used since nuclear energy was used to nuke 2 cities in WW2? I doubt it. It's not the energy, it's the user. Same goes for systems. Communism is neither really good nor really bad. It has it good and bad sides, but it's mostly neutral/good-ish.
There is the Socialist Federal Republic of Yugoslavia. It's the country where my parents were born. Unfortunately, it met it's end soon after my birth (I didn't do anything, trust me

). Anyone living in that country says it was the best system people can come up.
Tito was the leader. Everyone who was ready to work had a job. Everyone who wanted to study had free education. Free GREAT education. Many great minds came out of those schools/college. Everyone had GREAT free medical care. Everyone had food.
Looking at the current time, people in that time were actually living, unlike us who are just surviving in this retarded system. Working for over 8 hours a day just to be able to pay for my basic needs, 90% of the world capital in the hands of just a few % of the population....
Communism isn't broken, if anything capitalism is. Capitalism is actually the only system which is breaking it self.
So to answer the question. Fascism is a system where everyone who doesn't meet a certain standard is eliminated. If you ask fascists, women won't have rights, homosexuality would be punished by death and many more bad things.
Communism takes the away stuff from those who have to much, gives it to those who have to little. Everyone who is able to work has to work in order for the country to move forward. Education and medical care are free, everyone has food.
Don't take only the bad examples of a system and say the whole system is bad. Stalin was a maniac with power. A paranoid maniac with power.
On the other hand we have Tito who said NO to Staling (actually the only guy at that time who had the guts to say that) and had a GREAT country running. Although in the SFRY Tito used a red star to represent communism.
