I did Google things like “biodegradable straws choking hazard”, and “metal straw allergy” and found exactly jack shit to back up those assertions.

I googled “metal straw burning” and found “this injury can be prevented with the use of the silicone cap as it would act as a barrier,” so it’s not a problem either.

Just because someone is disabled, it is not a black check to make unchallenged assertions.
