If you don't have free will, you shouldn't be able to resist my suggestion. That's what it means to lack free will - to obey suggestion. If free will existed in this form, then your claim that free will doesn't exist will be wrong. If you want to say that some forms of free will exist and some don't, feel free to elaborate which do and which don't. If you want to say that compatibilistic free will exist and libertarian doesn't, that's completely reasonable, but "free will exists" is the accurate description of this situation.
