Deadline reports that the statement was quickly widespread anger. The outlet cites an LGBT group called Pride in London that posted a tweet with a photo asking Hammond if he'd like any ice cream from the company Big Gay Ice Cream. In addition, Wall's Ice Cream, the company that makes the Magnum ice cream treats Clarkson referenced, posted a tweet that said, "Hey @RichardHammond, it doesn't matter what flavour you prefer, ice cream is for everyone!"
We can argue about whether eating ice cream in a car is a good idea, but that's about the extent of it. Outside of a car, we think everyone should be able to enjoy ice cream, no matter what Hammond says.
