Also, here's Godwin himself on Godwin's Law, when talking about the alt-right folks who are now the backbone of the GOP: "By all means, compare these shitheads to Nazis. Again and again. I'm with you."

If it wasn't a choice for you then you have my sympathy, but I can assure you that is not a typical experience in the US.
You think we can't choose our religious beliefs?
I am sure you are more than capable of thinking of some, since they are pretty obvious. The biggest one that comes to mind is that political beliefs are not required to adhere to a dogma or a set of unfalsifiable superstitions. Also, they are much more fluid over generational timescales -- politics in the US today is vastly different than it was even 50 years ago. In addition, they are also much contextualized -- for example, your political behavior is a function of your local politics in addition to state and national politics.
> You think we can't choose our religious beliefs?
You can! But unlike religious beliefs, you can act on your political beliefs in secret via the ballot box, which frees you from the social consequences of doing so. Contrast this to religious beliefs, where people will notice what you do and do not practice, and potentially discriminate against you for it. The inescapability of religious practice (or its noted absence), and the prejudices that can come with it is why there are anti-discrimination laws for certain kinds of transactions necessary for you to thrive -- for example, housing discrimination based on religion is illegal, as is employer discrimination.
But in no case does Twitter kicking you off impede your ability to hold and act upon either your political or religious beliefs, so no legal protection for your Twitter account is necessary. You are not being oppressed.
Twitter/Facebook/etc don't ban most political affiliations. The only one that they really ban on sight is Nazis.
As a side note, indoctrinations are quicker and more efficient when done younger.
This is what makes religious indoctrination that much harder to shake off. If you truly believe that you will face divine and eternal punishment for becoming apostate, or will receive divine and eternal rewards for adhering to the faith, then you'd naturally take the latter path even if only out of your own self-interest. Breaking out of this mental model requires recognizing the psychological manipulation for what it is, despite having known no other mental framework.
By contrast, racism and Nazism do not manipulate you this way. They instead appeal to your senses of grievance, entitlement, and resentment, in a way that enhances your self-esteem. While this can also be difficult to break away from, the psychological barriers for doing so are a lot lower -- like, you're not dealing with eternal consequences.
But regardless, the topic at hand is whether or not religious or political discrimination are acceptable when it comes to using a platform like Twitter. I'd say "yes" in both cases -- Twitter isn't a vital service (compared to, say, housing, banking, or employment), and you not having a Twitter account does not inhibit your ability to hold and act on either your religious or political beliefs.
