"Each time you vote, you support the process" does not contemplate any other option besides not voting/boycotting. If the process is corrupt, if World peace is none of your business then any participation makes one complicit in the arrangements. These are not nuanced lyrics, nor does "There would be no war if not for me" contemplate any legitimate use of military force. Those are Morrissey's own lyrics, and what a plain reading of them demands. He chooses words purposefully and carefully. If he wanted nuance, he'd give nuance.
If it was plain he would have written "don't vote" - there are other options - he does want world peace to be your business. He's anti-war as "there would be no war" makes clear.
