You’re more than welcome to share your opinion. The issue I’ve found is that what’s considered harmful by different people varies quite a bit. Safe spaces online seem to run into a frequent problem of brooding persecution complexes which leads to having to self censor around specific individuals. This can lead to a very specific kind of bullying and in rare cases a hijacking of these spaces. More importantly for our purposes, it’s the assumption of bad faith that’s not compatible with what we’re trying to accomplish here- these spaces often become echo chambers for the most marginalized identities because no one is perfectly educated and omnipotent and any discomfort is viewed as problematic discussion and removed even in cases when it is tolerant (simply due to the perceived discomfort from having ones views challenged). They’re also fundamentally incompatible with intersectionality in a variety of ways, but perhaps most notably a person of privilege may be chastised for not recognizing their privilege or being educated and the person of privilege can use the idea of a safe space to censor a more marginalized individual on the grounds that it made them upset.
