Should streakers be classified as sex offenders

It is if you're streaking in front of children.

Then almost every nudist should be arrested and labeled as a sex offender, as those with kids generally have no qualms about being naked in front of them and encouraging their children to do the same. If anything, this is beyond what a streaker does, as it encourages children to be naked in front of adults. Hell, there are even nudist summer camps for children and teens with adult supervisors.
