I'd be one of the first to support mass ghoul extermination, so no, I wouldn't support the rights of basically cannibals. Psychos like Ogura should be put in a cage with a few hungry ghouls, or seeing a loved one maimed and eaten, then we'll see if there's a change of heart.
And even though this is the 21st century - where pretty much everything is being slowly accepted - ghouls would be treated the same as terrorists and hunted down. If it threatens humanity it has to be neutralized, simple as that.
