Absolutely nobody is claiming that.
What they’re saying is that that violence doesn’t define the religion, and that if you’re going to engage in that kind of action then the majority who practice the religion don’t want you. It’s peer pressure, and telling the vast number of Muslims that say their religion does not support violence that “you’re wrong, and we’re going to define your religion by the bad actors no matter what you say” is a great way to perpetuate the problem.
