I find that the trick - or at least the idea - isn’t to go out of the way to avoid such political discussions; it is to seek out spaces with some niche interest. Discussions would then naturally gravitate around the topic of interest, and political discussion usually doesn’t make sense in such a space.
An example topic is anime. Most anime are not political in nature, so commenters in ani.social don’t have the chance to go off-topic and discuss politics.
To use an analogy, let’s say you are a picky eater. You are given some food (think soup, salad, etc), but one of its ingredients is something you don’t like. Rather than try to pick out that one ingredient you dislike bit by bit (which can be tedious), how about adding condiments / dressing / etc to the dish? Enough of those and the taste would change, with the newly-added tastes having overpowered the one you dislike.
In terms of implementation, you basically have to curate your feed somehow. On Lemmy, the straightforward way to do so is to subscribe to topics / communities you are interested in, and participate in just those.
“Can you” as in “are you able to” or “should you”?
Anyway, yes on both counts personally. It’s like reviewing resumes with identifiers removed.
Otherwise, one would be judging the content with preconceived bias. IMO it’s a slippery slope to, and belong in the same subset as, so many other identity-related issues in society e.g. tribalism, identity-based politics, discriminition based on identities like race, etc
