I am open minded except a few things..

Being to open minded is also being open to lies.

That's's nice, what are though few things

Be open minded on this- I want to marry you. You are gorgeous!!

As well you should be. Besides, the term "open-minded" tends to be misused, from meaning that one's mind is open to new ideas or opinions, to a more "anything goes" or "no judgment" definition.

So many have closed minds and are not open to new ideas and new things,

What are those few things?

That's fair. If your mind is too open you never know what kind of garbage people will throw in there.
