No it isn't. They used to say the same about gay activism, women's activism, black activism. Now, calling it terrorism in my opinion is too far fetched.
Instead it's simply the same old attacks on civil rights the USA and Western society has slowly been grappling with for about 100 years or so. A drop in the lake of history. There will always be a pendulum on these things as lines are redrawn, and pushback from those fearful of change.
Or in Charlie's case, lacking the empathy to see them as equal human beings and not projects to be converted.
