I mean you are free to do whatever you want literally whenever you want. From healthy outlets like eating a chocolate bar cause you want one to something dumb like drinking Gasoline.
Why would you want to though is the question?
The idea of "Religious Freedom" is pretty nonsensical when you think about it. It came to me after the Thoth God's rituals (
https://ancient-forums.com/threads/...powerful-joining-brothers-and-sisters.295144/ get involved if you haven't already ) and all the word Religion means at it's, at it's core, is a science of the spiritual: and one is always free to be ignorant if they want.
Our Might Glorious Father Satan is literal Freedom itself. Like the literal freedom based properties of the Fehu/Uruz/Ansuz runes themselves. Akin to the Badass Super Satanically Charged older brother who's the very concept of Freedom itself that all derives it's power from. With that in mind he has Stated without question "I will allow the dictates of one's own personality."
In chapter 2 though of the The Al Jilwah it states
"I requite the descendants of Adam, and reward them with various rewards that I alone know. Moreover, power and dominion over all that is on earth, both that which is above and that which is beneath, are in my hands. I do not allow friendly association with other people, nor do I deprive them that are my own and that obey me of anything that is good for them. I place my affairs in the hands of those whom I have tried and who are in accord with my desires. I appear in diverse manners to those who are faithful and under my command."
"I give and take away; I enrich and impoverish; I cause both happiness and misery. I do all this in keeping with the characteristics of each epoch. And none has a right to interfere with my management of affairs. Those who oppose me I afflict with disease; but my own shall not die like the sons of Adam that are without. None shall live in this world longer than the time set by me; and if I so desire, I send a person a second or third time into this world or into some other by the transmigration of souls."
In this case the layman's terms for this means you must suffer the effects of the causes you create. If you go with someone who's not an Zevism than there will be effects to that cause. You must brave them, grow from them and reach out a helping hand to help another rise above.
If you want to be with someone just cause than you do not deserve anyone because you aren't going to put effort into the relationship. If you're lonely, and this is a lonely path, than you must understand that first loving yourself is MASSIVELY important. Like the very first step in getting a relationship. How can you treat others with respect if you don't respect yourself: because by not respecting yourself you don't know the concept of respect to start with. Than there is the fact that self-love, self-trust, and self-confidence teach you that others have that. You must learn to be Human to act Human and treat others with Humanity: and who would want to be in a relationship with someone who's not human/treated with humanity?
