I'd actually advise you to do the opposite of what Orwell recommends.
Policy stances are meaningless without a broader scope of what society means, and each stance on an issue should take other ideas with some level of consideration. For example, let's say that you believe in an active fiscal policy, but you distrust the ability of politicians to implement difficult policies, then it would not make much sense to push for active fiscal policy. Or let's say that you don't like racist expressions, but you also believe in the freedom of speech, you obviously have to account for the smaller issue in the perspective of the bigger issue, otherwise you are a jumbled mess of inconsistencies.
To that end, if you are interested, I would advise taking on some research on the nature of most of the different ideological views out there, and in particular taking an interest into political philosophy/ethics, economic thought, and perhaps socio-political understandings.
That way, you can work from broad ideas down to more specific issues. A case-by-case approach will lead to being bogged down by the sheer number of cases, and the amount of data that exists for a particular case, so instead, I would argue to work from general principles first, then for perhaps a big important issue, taking more time.
