I suggest you look up the definition of animosity then. I've seen it from at least 4 different posters posting with resentment and hostility aimed at the OP.

Definition of ANIMOSITY: 'ill will' or resentment tending toward active hostility  : an antagonistic attitude

If people resent their workarounds not being acceptable and display anger about it, they're showing animosity.

I've already said I don't think the RSR thing is a big issue, but I do think SM is aware of the issue because they've received enough complaints about it that it was considered being put back in as Ratscloset has stated. Do the work arounds take a lot of time? Not really. Do they take more time than having it done automatically by Poser/DS/Cararra when they open the folder with the RSR? Sure. Certainly it's not a lot more time, but cumulatively, for people who install/uninstall/reinstall repeatedly as has been suggested by the OP, it's still time wasted. Maybe it isn't enough to bother you or me but maybe busy people might have more of an issue with it than we do. Walk a mile in the other person's shoe? It's still good advice.
