There is a line between being respectful, unprejudiced and accepting human beings, and being politically correct to the point of being oblivious and even dangerous. It is sad that in our culture this line is often crossed during tragedies, particularly those committed by privileged non-minorities. While it is incorrect and unfair to blame someone's actions on their race, religion or economic status, it is important to recognize these factors in order to understand the root of their behavior.
Our society holds an incredible double standard, associating crimes carried out by minorities with an entire group of people such as African-American and gangs and Islam and terrorism, while refusing to the same with similar crimes such as white men and school shootings. This overtly racist convention shows the toxicity of selective disassociation, a process that we go through as a society, attempting to separate a person from certain parts of their identity in order to prevent their actions from reflecting poorly on a group of which they are a member.
When we do this, we fail to understand a person's identity as a whole and it leads to an unfair assessment of their actions. In order to combat this inequality, we as a society have tried to totally disassociate violent individuals from any and all other social identities that they hold, which only magnifies the original issue. Instead, we must try to understand hateful people as whole individuals, taking into account the many facets of their identity. Perhaps the oppression that their race or religion faces was a factor that caused them to do something awful. This is an issue that can be addressed, but only if it is brought into the discussion to begin with.
Rather than illuminating labels, we must change how we use them as a society. Rather than creating groups that divide and create tension, we should seek to understand peoples' various backgrounds and cultural influences. Rather than projecting the actions of an individual onto an entire group, we should understand how the dynamics of a certain group could cause an individual to do something terrible.
As people, it is natural that we have differences in looks, beliefs, lifestyle and opinions and it is natural that we should congregate with people who share these things. However, it is unnatural for us to hate and hurt one another for these things. Rather than fighting the innate aspects of our being through attempting to disassociate from our groups, we should fight what is unnatural by using our experiences as members of a certain race, culture or religion to spread awareness, equality and love.
