Yes. It is wrong to say it doesn't interact with bryonic matter. It interacts only gravitationally. So the OP's question is basically, will a space craft be smashed only because of gravitaional energy? My guess is probably right and it is - no, things are "smashed" because molecules come close enough that they start repelling each other, converting the kinetic energy o the molecules into bond energy which above a threshold causes the bonds to break (at lower speeds, the bond energy is not enough, so it is dissipated back into kinetic energy and molecules will fly to lower energy state which will be farther apart where they are not repelling, physically observed as "bouncing"). So it is electromagnetic force that causes something to "get smashed" or bounce, and that is not how dark matter interacts.
So if it is possible to create a canon of dark matter, it will have an ingenious design to only work with gravitation and will only "bomb" gravitationally.

You know, I see still anonymous posts about hooked cross. What a shitty website.

Yes, and I was not allowed to post it without logging in so it shouldn't count.
