Food for Thought - What do YOU Think?

Yes, this is food for thought, and I’d really like to know what you think. Sometimes I just get these random thoughts or questions stuck in my head. Here are a few.
Which is correct: Politics is or Politics are? Grits is or Grits are? Family is or Family are? Variety is or Variety are? Mull these over, then share what seems right to you, okay?
And speaking of food for thought – What a waste!!!!! I’ve never wanted to simply think about food! There is something better to do with food than think about it. Right?
