People with weak minds and convictions are offended by people who disagree with them.
It is unfortunate that a person feels a need to justify themselves for speaking their mind.

There is no medication available at this time that will make people stop looking for faults in others instead of looking (so they can correct themselves) for the faults in themselves.

If you do not feel well it means that something is wrong.
It is our own responsibility to figure out what is wrong.
