Suggest you look up the definition of anti-semitism and only use accordingly. Using that term freely based on your feelings and emotional state rather than the actual words you are responding to, only serve to dilute and weaken the ability to combat true anti-semitism IMO.
I don’t know if there is a similar danger with misusing the term terrorism. It is mostly used by media and nation states to dehumanize the enemy, justify disproportionate responses, to justify large civilian sufferings/casualties, and to justify large military budgets, e.g., the war on terrorism.
Obviously a nation state should protect itself against any form of attack (whether labeled terrorism, direct military attack, or social media manipulation), so I don’t see the use of the term terrorism as critical. If a civilian bus is bombed, the state should respond accordingly whether it is defined as terrorism or not. The DOJ and FBI can parse definitions during law enforcement actions, but they aren’t going to be affected by the overuse of the term.
But I will concede that right wing terrorism is a growing threat in the US, so maybe the overuse of the term weakens the ability of our population to properly respond. So I agree that when dealing with US domestic acts of violence, a proper use of the term terrorism is important, but when dealing with foreign policy and justifying military actions, probably not
