Why is communism bad?
and why do so many Democrats support it to this day​

Communism puts too much power into the hands of one person, and since the natural human tendency is greed, the person will abuse the power. The Democrats support socialism, and the goal of socialism is communism.

Most mainstream media broadcasts censored news. For example, CNN claimed that Trump accepted and conceded in the wake of the 2020 Elections (with election fraud). The post was likely taken down. However, Trump did not concede.

This answer may be controversial for some, but I am just sharing my perspective. Please feel free to let me know your perspective.

The cueca is a musical genre and a dance of mixed loose couples of the late eighteenth century. The dancers, who wear a handkerchief in their right hand, draw circular figures, with turns and half turns, interrupted by various flourishes. Generally, it is considered a dance of conquest of man to woman, although it does not necessarily have a loving motive.

The cueca would have originated in the zamacueca and this, in turn, in the Spanish jota and fandango dances.
