Data validation is a totally different thing than strong typing. The latter ensures your codebase is consistent regarding various data types flowing through it, whereas data validation asserts runtime input compatiblility (of course from outside world, AKA application boundaries) with what the code expects.
While strong-typing is not a must (however makes design/develop a whole lot easier and insightful,) but validation is always required, no matter what programming language or platform you use.
If that helps, as a metaphor, data validation is like the security guard that verifies legitimacy of people entering a military base and makes sure everyone is suited with their formal camo with visible names/ranks, while strong-typing is like the set of military rules that defines the hierarchy and the chain of command.
As developer i learned and will teach also defend programming.

I strongly advice you to be open for different views. Listen and try to understand the arguments. Try to avoid putting people in a box, saying they didn't actually did any real work, they missing points etc etc. Changing given examples to proof your vision.

We're a place where coders share, stay up-to-date and grow their careers.

@jfbrennan & @babakks
nice clarifications.
