Kudos for raising this issue!
Racism has a very precise definition which is "the belief that all members of each race possess characteristics, abilities, or qualities specific to that race, especially so as to distinguish it as inferior or superior to another race or races."
The problem nowadays is that the term is used for political reasons only, based on the marxist concept of oppressor vs oppressed. Some people are altering its meaning just to justify votes for their preferred political party.
