A lot of interpretations for sure when people start trying to compare stuff.
At it's most innocent, when someone says 'Hey! Your thing reminds me of XYZ, which I love too!" , then it's less dragging down and more someone stating that they dig the theme of the art.
But yeah, when someone actually slags someone for not being 100% original just for drawing a giant robot, which was first done decades and decades ago, then it's just someone looking for a reason to complain.
We all get inspired by different stuff, so having similarities (without outright plagiarizing, which would be a real issue) or inspirations is what art is all about. Making something cool so someone else feels like making something cool.
Number one thing to do is just not be a jerk on the internet, which we can all manage if we try hard enough. haha
