You bring up two issues. You ask if you can converse with the devil/demons. I would advise you never to converse with the devil or demons. As far as whether or not the devil or demons can hear what you think, I wouldn't worry about that. Just stay with God.
The Bible teaches us that the world is in the power of Satan. Therefore, we mustn't love the world.
However, the Lord wants to save the world from Satan - he loves the world.
Reminds me of something that happened to me when I was very young. I saw something that looked like a purple grape. I liked purple grapes, so I took one and ate it - no voice told me,"Thats not what you think it is." It turned out to be an olive - I didn't like it.
To begin with I will remind you of Leviticus 18:22, where God says homosexuality is an abomonation. The Democrats all say there is nothing wrong with homosexuality.
