They're not fighting anything. Your straw from a bar in a first-world country reliably ends up in a landfill, among heaps of other plastics. Far away from any turtles.
The Pacific garbage patch is mostly from fishing nets, and the other sources of plastic pollution are mainly from riverside cities too poor to have good waste management.
The whole plastic straw scare is so obviously attacking a minor non-issue at significant personal inconvenience, that I wouldn't be surprised if it was planted by climate deniers to make people angry at or cynical about actual environmentalism.
