Correct, you’re not required to swear on the Internet. That’s why there are a trillion other words to use if you’re not comfortable with it. “This kind of stupid packaging foam.” “This kind of annoying packaging foam.” “This kind of ovnoxious packaging foam.” If you want to say “fucking”, then you can just say “This kind of fucking packaging foam.” The censorship is useless and distracting. Commit to the word you want to say or use another word; nobody’s going to punish you for swearsies here.
