>I believe this is a slippery slope fallacy that weakens your argument Is it a slippery slope fallacy? If we do A then B must happen and I think if we do A then B will happen are two different claims. The latter does not explain the reasoning and is thus not a slippery slope. To give an example. If we legalize same sex marriage, polygamy will become legal because of it. This is a slippery slope slope because it is directly saying one will cause the other just because the first one will happen. I think if we legalize same sex marriage, polygamy will eventually become legal. (Unsaid reasoning behind the opinion: Upon re-evaluating the existing laws in our push to legalize same sex marriage, combined with an existing acceptance of polyamory, we will see that there is no justifiable reason to keep 3+ adults who wish to form a family from doing so, and though the laws will be a bit more difficult to accommodate them, we will lose any sense of 'wrongness' that is used to justify the ban.) This is not a slippery slope. The original claim is just not displaying their logic behind their opinion, but that does not mean their logic is a slippery slope. The difficulty is that in the English language, the two can be written the same way and one won't know the intent without asking the author.
