Basically the best way to avoid being beaten down by the same gang over and over and over again is to take your beating and move on. A single gang will not roll your hideout repeatedly unless you give them a good reason to do so.

(If I was driving a war points gang, whining in a public forum would be good enough reason for me.)

Suck it up, quietly ramp up your troops, get some decent stats and war weapons, and make it harder for them next time they come calling.
