"A hate group is an organized group or movement that advocates and practices hatred, hostility, or violence towards members of a race, ethnicity, nation, religion, gender, gender identity, sexual orientation or any other designated sector of society." Is the Wikipedia definition of a hate group. The importance, in my opinion, of this definition, is that it is the group's purpose. There are many groups who have hateful individuals inside of them. I have seen many cite the actions of individual member's of Black Lives Matter saying or doing something hateful, and claiming that that makes them a hate group. But that is hardly a fair way to go about it.
Hate is not a tenant of BLM. To claim it is a group is a hate group because some of it's members do or say hateful things is a useless definition. With a definition that broad, every political party or movement that has a few million people as a part of it would be a hate group. The Democratic party, the Republican party, the NRA, Green Peace, Black Lives Matter, All Lives Matter etcetera. They would all be labeled hate groups. With a definition that broad that doesn't distinguish between, say, the GOP and the KKK, it would be useless.
What distinguishes the GOP from the KKK is that the KKK has hate in its tenants. It's purpose is the spread of hate. That is what defines it as a hate group. Therefore, BLM is not a hate group. CMV.
