Your post highlights one of the biggest problems of youth today. You think that you should be spared from anything that might "hurt your feelings". In modern society, boys do not go through the same rites of passage that were ubiquitous in tribal/primitive cultures and therefore are not made to associate hardships with gaining maturity and status in the male community. In these rites, boys are expected to endure intense physical and psychological trauma - and frequently are expected to do so without showing any distress. What you need to understand is that it is hardwired in the male brain to show aggression to other weaker males. I'm not saying it's "right" but any time you put yourself in a situation with older males, you must accept the possibility that you'll be treated harshly. Develop the confidence and resolve to not let it bother you, and just move on. Don't show distress. Build strength in yourself instead of asking others to compensate for your weakness. If you have a hard time with guys in a multiplayer video game, just wait until you get to high school and have to shower with seniors. Toughen up son.
