The entire linked post is identity politics.
"They're not like us" is identity politics.
"They voted differently than us because of their identity" is identity politics.
Sorry friend, it seems you love engaging in identity politics, otherwise your political positions would not be gripes based entirely on people's identity. Your post is like claiming you don't discriminate based on skin color, then in the same breath, saying that people of a particular skin color are bad.
You certainly don't need to agree with me or anyone else, you have as much right to an opinion as anyone else but hiding behind that button just to try to hide a dissenting opinion just proves you're on thin ice. Use that button for things which are clearly beyond the pale, and/or violate the board rules, use your voice to show disagreement.
