I am not sure what kind of strange bubble you live in but that is objectively not true. Most people on the left are most definitely not communists. You either do not understand what the word communist means, or you live in a very strange bubble or country where everyone on the left is described as a communist.

Communism (from Latin communis, 'common, universal')[1][2] is a left-wing to far-left sociopolitical, philosophical, and economic ideology within the socialist movement,[1] whose goal is the creation of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange that allocates products to everyone in the society based on need.

Most people on the left are NOT pushign for common ownership of the means of production and distribution and are most definitely not in support of a centrally planned economy.

This is also the danger of extremist views, they think anyone who does not subscribe to their extremist viewpoint is against them and the enemy when in reality, 90% of the people on the left would not agree with communist ideology which has failed in reality time and again.
