Pamela Geller has the right to have a mouth and brain full of shit, and invite people to come and listen and watch her spill that shit out of her mouth. She has a right to form an organization that celebrates that shit that comes out of her mouth. She has the right to insult any idea, any religion and any group of people, using the most vile language she can think of. She has a right to say things that make her look like a rabid, insane, hate-fueled harpy, so long as they are not threats of violence against people. And she exercises that right regularly.
You do NOT have the right to commit violence against the racist, hate-filled people that support her and attend her events, nor against her.
Pamela Geller is no more a free-speech advocate than a group of Klans members who wear sheets, wave confederate flags, and use the "N" word on a march through Ferguson, Missouri, or a group of people that hate the USA and piss on an American Flag outside an American Legion Hall, or a group of men who stand outside a gathering of women at a civic center and call every woman who enters a slut, a whore, fat, ugly, unfuckable or stupid.
I've said it before, I'll say it again: I couldn't count how many times comments about atheists from Muslims and Christians have insulted me... yet, I'm still not calling for the death or punishment of anyone for offending me.
Freedom of speech - including the freedom to insult - is a human right. And that means no one should die for blasphemy. No one should die for insulting anything or anyone. No one. Not even people with a mouth and brain full of shit like Pamela Geller and her followers.
And for a counter to the narrative of the two killers in Garland, Texas and other extremist, murderous men who claim to follow Islam, follow Quranalyze It on Facebook - it reflects the kind of thinking I've experienced from many of my Muslim friends (oh yes, I do have such).
Also see the blog I get insulted. But I don't murder; it includes how the Qu'ran actually defends freedom of speech, and a story about the Prophet Mohammed that murderous Muslims that kill in the name of defending Islam either forget, don't know or ignore.
