For those that are active in voicing criticism, please exercise a degree of empathy when doing so, especially concerning people who work hard to make things and are not harming anyone else in the process. Creating isn’t easy, and it shouldn’t be discouraged.
Please criticize. It’s important that you do. But do so with kindness and purpose. If the opinion doesn’t add value and the person on the receiving end isn’t harming anyone with their creation, then it might be a good time to reconsider voicing it.
