I had to google "Oakland sex offender protest" to find out what you were referring to. You didn't have a link. Anyway, this is the story I found:https://www.abc10.com/article/news/local/california/sex-offenders-protest-their-right-for-travel/282998981
In all fairness, it isn't liberals protesting the arrest of child sex offenders. It's the sex offenders themselves protesting the laws against them. That's very different than what you posted. I had to look it up because I was thinking "That ain't right! Everyone I know supports arresting child sex offenders."
Unless there was something else that you were referring to? I can't imagine anyone being in support of child sex trafficking. That's just disgusting and evil.
