"They wouldn't have gone to the expense of making a new line if they didn't have reason to believe they were filling a gap in the market and that it'd sell." So naive - it's called creating a need and they do it because their current sales are at saturation point. In other words TO MAKE MORE MONEY
"It is not sexist to respond to market research which suggests a group of people want different things from a product than another group." I think you need to learn more about how 'research' is conducted - selected participants, carefully worded questions, question selection, size of study... NEVER accept 'research' at face value. Simplest example of how research can be a load of bollocks - correlation is not causation

Frankly even DOING a study based on how women v men eat a foodstuff is sexist in itself.
"Or are women not allowed to ask for things they would like to see in a product?" I think you're missing the point, this is a product for all why do they need to ask WOMEN in particular about how a product not specifically used by women can possibly be improved?
"It's going down the same route of pink razors for women at a higher cost." Ugh don't get me started! "Women's" razors are shite and 3x the cost of "mens", I use "mens" razors much better and cheaper.
Spoof or not it's sexist crap!
I hope sales go DOWN as a result
