If you have the means to do outreach and enjoy it, go for it!
If you are not a social person and/or don't feel like producing memes, videos, or working on grassroots efforts, that's fine as well.
Just use your other means to support those who do and support businesses/business owners who are principled Voluntaryists.
Not everyone has to be an evangelist for liberty. Just being a more ethical person through self-knowledge, peaceful interactions, peaceful parenting, and treating others with respect by the N.A.P. is an improvement to the world.
