Not and but

The words 'not ' and 'but' are a dangerous combination.

To depoliticise them, let me give an example against myself.

I am not stupid, but I don't understand algebra.

So, any sentence containing "not " and " but"  must make you think.

Take out the " not " and "but"

Think again.

So, that sentence should read " I am stupid" 

Try it again.

I am not racist, but...

I am not homophobic , but..

See? 

Don't do it.
