So I read your criteria, and I noticed something...
I almost never mean to be aphobic, in fact I honestly seem to be an angled loveless aroace (I experience platonic and sexual attraction (? Not really attraction but libedo) more) but I often use the word love
Likely due to the fact that
1. Allos seem to do that, partially doing it to fit in
2. I have slight bullying / social exclusion trauma thanks to being neurodivergent. And if I say 'I respect you' or 'I care for you' or something else more similar to my true experience, it feels slightly passive aggressive which I do not mean at all
Usually, when I use any labels for relationships, I mean like, the level below
So, what do I do to make my personal blog more aspec friendly ? /gen
Not easy, but surely really interesting.
Using the word love is not straight-up aphobic. It isn't a "wrong" or "bad" word in any way.
Love is a difficult concept, and the definition varies from one person to another, so what may trigger somebody may be perfectly fine for someone else.
I personally prefer not using it (or putting an alternative wording near), but it is mainly due to my pettiness, my wish to be as inclusive as I can, and the fact that sometimes it bugs me to read/think about it. But this is my thought, and it's based on my personal relationship with the concept of love in our society. It can be different for other people. (It probably is).
You don't have to act like an allo person to fit in: if something makes you uncomfortable, they will respect you. Otherwise, they're probably not the group of persons you will want to fit in.
You can have really valid reasons to use the word, and nobody can tell you that your feelings and your sensibility on this matter are wrong. Just pay attention to other people, too.
The "I love you"s aren't what makes a blog aphobic.
If you think you could support the aspec community more, here are some suggestions. Obviously, those are only a few, but they can be valid point from which you can start. (Is it that obvious I really enjoy lists?)
Aspec related posts! If you see a cool art, an interesting discussion, a rant you can understand and relate to (or one you can't, but you still want to support them), an informational post about a label not well known, even just some random "aspec people are valid" post, reblog them! (Every time I'm randomly scrolling and I see one of those, it warms my heart!)
Trigger warnings tags. To tag things properly is important, but, often, people forget tws for things like romance, sex mention, or aphobia. I find them quite useful, and probably romance/sex repulsed people do too.
No aphobia. Seems obvious, but pay attention that none of your posts contain messages that can be offensive for aspec people. This includes but is not limited to: "love is all that matters"/"love is love" signs; exclusionists (people who don't belive aspecs are part of the lgbtqia+ community) posts; posts that say that a certain label under the aspec umbrella doesn't exist; and every other message that invalidates our experiences and feelings.
Another pretty obvious one, not strictly related to the blog as it works irl, too, do not invalidate aspec people's experiences. This includes fictional characters.
Be open to dialogue: if somebody tells you something is making them uncomfortable, or that you could do something better,be open to changes and constructive criticism.
This is pretty much all I can think of right now. Those are general points that are always useful to keep in mind, but, obviously, there can be more.
I hope this is at least a little bit interesting and helpful.
If I said something wrong, feel free to correct me!
