People who like the Confederate flag are more likely to feel hate against another group and care more about putting others down. The Confederate flag stands for superiority and actively enslaving another group of humans who they feel are lower lifeforms.

The gay pride flag stands for equality and inclusion. The rainbow is meant to symbolise all groups coming together with no subjugation. People who want the rainbow flag are more likely to want it as a symbol on its own, not want it as a symbol of war against another group.

The difference is people who like the Confederate flag are lazy cowards who think they are entitled to others doing things for them; Gay pride flag bearers are bravely risking attack to show that they stand in unity for an open and inclusive community.
