I don't categorically oppose religion

I suppose I'm what the media calls a "new atheist"--I'm an atheist and I advocate for atheist causes.  Many people see opposing religion as the primary atheist cause.  But in my case, this is not entirely accurate.  I oppose many religions, but I don't know that there is anything wrong with religion per se.

I oppose most religions I see around me, for many reasons.  Faith is seen as a virtue.  Supernaturalism is encouraged.  Voices from ancient societies are thought to have moral authority.  Special privilege and admiration is given to people who happen to enjoy ritual or awe (not that there is anything wrong with enjoying those things).  And of course religious people systematically advocate many specific causes that I oppose, such as Creationism and abstinence-only sex education.

I don't think any of these are essential properties of religion.  Perhaps you think that at least some of them are essential--for example, many people think that if there are no supernatural beliefs, then it's not a religion.  But even so, you can certainly imagine a religion that places a much lower value on faith, does not value ancient morality, and does not advocate such terrible political causes; I would oppose this hypothetical religion far less vehemently.

To make the hypothetical more concrete, what if I moved to some part of Asia?  I know very little about how religion interacts with society on the other side of the world.  In that situation, I would tentatively still oppose religion, but it would be a kind of shallow opposition until I learned more about the specific harms caused by religion in that culture.

Even in the US, there are some "religions" that I have little to no problem with: Unitarian Universalism, Secular Judaism, and the Sunday Assembly.

I put religion in scare quotes because I've heard many atheists argue that these are not religions.  There are likely reasonable arguments to be had about the best definition of religion, but my impression is that atheists are using motivated reasoning; they want to be able to say concisely that they oppose religion, so they're motivated to argue that things they do not oppose do not count as religion.

I don't think it's useful to get too attached to any particular definition of religion--if you're interacting with UU people (who see themselves as having a religion), would you rather argue with them about what counts as a religion, or would you rather work together on more productive causes?  (Disclosure: my boyfriend is ex-UU.)  Another advantage is that no one can cheat their way out of criticism.  If you say you're spiritual but not religious, maybe because you have a personal relationship with Jesus but don't participate in any churches, that doesn't give you an out.  If you think that my atheism is a religion, I think you're really stretching the definition, but also it doesn't matter.  If there appeared an atheist organization that had a hierarchical structure and performed rituals and sermons in a church, it could more plausibly be called a religion, but that still wouldn't make it wrong.

TL;DR: I oppose the major religions in my present society, but I am unwilling to generalize to everything in the world, present or future, which could plausibly be called a religion.
