Honestly, I believe the way that people should communicate on the internet is through respect. To treat others the way we want to be treated. There are so many instances where I find people saying and writing cruel things to each other just because the other calmly said they did not like a certain song or book. What the heck? Sorry I can go on and on about this and I apologize if I didn't answer the question correctly.
Have u ever really been Look at them when they r speaking. Trust me. Even though that u r not able to knowing the words but u will sense the meaning. From body language. Their expression etc. And every one r free to talk. There isn't much to take into account about the law
