Further more the TSA agent told me that "anything in a squeezeable container greater than 3oz was a no no!"
When did this new rule arrive. The web, the placards in the airport, etc, all prohibit liquids, gels, and aerosols, not pastes! There are some countries that specifically state "No Pastes" right on their signs but I have never seen this in the US.

You got a nitwit of a screener who just made things up - there is no such rule, however 3.4 oz is the limit, but it has nothing to do with a 'squeezable' container. They consider a paste the same as a gel.
Your 4.2 container was over the limit, hence the involuntary forfeiture.
Next time, try harder to artfully conceal your over-the-limit liquids and gels
