specifically : a historical process by which the semantic and connotative status of a word tends to decline
One thing I love about being on this instance is I'm blissfully unaware because downvotes are disabled. This is what I see.
American Democrats think anyone who criticizes their actions -- such as opening more concentration camps, continuing Trump's wall (yes, that wall), arming genocidal states, and taking power away from the working class -- anyone who criticizes these things MUST be a right-wing shill.
I'm not joking. That's really what they think. I get it all the time. Hence the downvotes, and hence the unfounded claims about OP.
