This implies that the difference actually matters. In both cases there is a political goal behind the actions. Yes, printer driver software itself is very different from sexual and gender orientation, but wanting for the printer drivers to be free is a political statement and principle, and so is the uplift of LGBTQ+ people and celebrations of PRIDE month. Both are political despite being about distinct subject matters.
You can disagree with the politics in question, but to say that FLOSS has no room for politics is itself a political position, leading you to a paradox!
Yes, it matters. You can try to distract and do as much mental gymnastics as you want but everyone rational can clearly see that one thing is doing politics for software (free drivers, open source, no DRM, …) and the other is about virtue signaling about subjects that are completely unrelated.
Btw, feel free to label me however you want (others did already), which shows that they have no arguments and resort to pidgeonholeing and name calling.
