It's understandable to fear life as one knows it to completely change, and since the most famous enemies of capitalism were communists it makes sense to assume that "my enemy's enemy..." is in place. The reasons you hate communism aren't exclusive to communism, and everyone here, its safe to assume, hates the downsides of communism as much as the downsides of capitalism.
Think about criticism of capitalism the same way as someone criticising Luigis Mansion. There are bits of it that absolutely suck, and would like to change (locking a boss behind a 5 minute cutscene ffs), it doesn't mean that if they had added a 'skip cutscene' button we wouldn't all be slightly happier with Luigi's Mansion.
Or think of a country as a family multiplied on a huge scale. It's ok to hate the way your parents run your house, if you worked twice as hard as your sibling and got a percent of their allowance you'd be pissed off. It wouldn't mean you hate your family. Or that you wish your family were the Manson Family, it would just mean, you think aspects of it is unfair and you'd like to address it.
