A person who holds the view that organized religion when considered throughout the centuries has been a destructive force in society, wrongly believed is that all are also agnostics or atheists, but a great number of faithful theists also see organized religion as harmful to society and choose to follow their own path to god.
when considering the crusades, September the 11th, the holocaust and the Spanish inquisition the anti-theist concluded that religion had caused great harm to society.

Actively opposes a belief in gods of any sort and to institutions built around belief in a deity. They believe that religion is harmful to individuals and society and that it impedes scientific progress and encourages immoral acts.
An anti-theist may see religious harm in the brainwashing of children, faith healing, circumcision, holy wars, terrorism, the inquisition, blood sacrifice, and discrimination against homosexuals and women.

An antitheist is someone who actively opposes religion or even theism in general, which they make known in an egotistical, cynical, and overall self-righteous way. Ironically, a lot of them seem to enjoy berating and judging the same religious people that they claim behave the same way towards them. Antitheists often think that they are intellectually superior to everyone else, yet they fail to realize that some of the greatest minds in history were theists. These include Tycho Brahe, Galileo, Francis Bacon, Issac Newton, George Washington Carter, and Antony Flew (who was originally a staunch atheist for over fifty years before converting to deism).

However, there is a difference between being someone who simply doesn't believe in God and being somebody who goes out of their way to bully and guilt people for believing.

And before anyone assumes anything, I myself am agnostic.
When an antitheist justifies judging someone because they have been judged, it just goes to show how hypocritical they are.

People who don't realize they turned atheism into a religion. Mock Christians for.not questioning what they are told. Yet get mad when one questions them. Usually attack a Christian Twitter account. Don't realize that most early scientists where religious. They think they are superior. Yet don't realize that they follow men, take their word for it. They try to convert everyone to atheism. And try to convert atheists who don't give a crap about religion, to join them.
That anti theists said I was shoving my stupid silly beliefs down their throat. Yet all I said was bless you when they sneezed. Then the hypocritical atheists tried to deconvert me. By shoving their beliefs down my throat
