If you believe in open source, then you need to be respectful of copyright law. It is the foundation for open source licensing.
I don't see how that follows. I support open source, that is, the free distribution of software code. Open source licensing is just a necessary evil to account for the fact that copyright is anti-open-source by default. A few decades back, when the US and other countries required registration to copyright works, open source licensing would have been a ridiculous suggestion (except for copyleft licenses), even though open source itself would still make perfect sense.
