Labels are just that: labels. They're worthless and should be torn off as soon as you've known the person for more than 5 minutes. People aren't clothing, or anything you can buy in a shop, we don't need labels because no mere label could ever tell people who we are. Labels simply exist for others to be able to make judgements and predictions about us with little knowledge about the individual, the label doesn't actually change the person or even be close to being correct.
Even if the label is "correct" and you think yourself to be whatever the label says, that's still wrong. For example, lets say some people label me as a computer geek and a furry. The labels are "correct" in that I do things that match up to people's expectations of anyone with a "computer geek" label and I do identify as a furry but that doesn't define who I am. It's like with your job: you may tell people that you're a chef or an author or whatever but that's not who you are, that's just your profession.
What I'm saying is that even with a million labels applied to you, they won't come close to explaining who you are and people shouldn't judge you based solely on the labels other people have applied, even if those labels are "correct". People are who they are, not what you think they are and not whatever you've decided they should be based on 2 minutes of interaction with them, if that. Labels are merely tools to help people identify others and make predictions and judgements, but they're inefficient tools that people have become too dependent on and now they're too reliant on their labels to actually think for themselves. Were this an ideal world there would be no labels, but it's not and society has become too attached to their precious labels to be able to survive without them, so we can't just destroy labels from the common social consciousness.
At the end of the day, if people are so shallow as to apply incorrect labels without thinking and make judgements based on those labels without even taking the time to check if they're correct or not, they're probably not worth your time.
Just my thoughts at the moment...
