My opinion is this.
Charlie Kirk was not a force for good. He used controversial speech to build himself a platform and a large bank account. Debating and baiting students when you are a grown adult is weak and shows that you are not above “punching down”.
He is not a matyr for free speech or politically assassinated. He was publicly murdered for a reason we don’t know yet, and may never know. So it’s all speculation.
BUT, he did not deserve to be shot at or die. No one has the right to take another persons life in civil society no matter how heinous they think the other person is.
The current US president has said far worse which people have supported, but that doesn’t mean everyone has to stoop that low. Kimmel was irresponsible with his speech, he should be checked but not cancelled.
