Basically, looking for specific critique while ignoring all others is "selective listening." Generally, the term holds a rather negative connotation.
Critique will be given in these forums, because the users aim to improve those who they are critiquing. They have the best intentions in mind with you as a spriter/map maker/artist in general. I daresay picking fights with them over their critique is undermining their good intentions. Naturally, such an act can cause a shitstorm like what we see throughout this thread.
Simply, you post here, critique will be given. Whether you accept said critique or not is up to you, however picking a fight with those that critique is unwise. If someone does happen to give bad critique, he/she will be corrected, I can ASSURE you of that.
