We should.
What communists really want is to have their every need and desire magically provided for, as if they were fundamental rights. In other words, what they truly want is called post-scarcity: the absence of an economy.
Communism and socialism are economic models. There exists scarcity of goods and resources and therefore they must be economized. There's a system that chooses who gets access to said scarce resources.
Socialism is sold to people as though it was post-scarcity. People think they'd be living comfortable "secure" lives where everything is guaranteed and provided for. Ah yes, the fabled memetic fully automated luxury space communism.
People who buy into this will probably end up doing forced hard labor in a field somewhere should communists actually come to power. They will not get to do what they want, they will work wherever the state puts them to work under penalty of death by firing squad. The state has no choice, anything else means mass starvation and millions of deaths.
Pity is far too lenient a reaction towards such reality distorting naïveté. If left unchecked, they will win elections and actually install socialism in your country.
We have a better chance of achieving post scarcity by collapsing capitalism with relentless automation.
