It's just banter. I don't think any of shacabka Somalis really care about Somaliland. It's just the nationalists who do want to see Somali Republic rise from it's ashes.
Yea, that's probably so. But it would surely be more effective if it was based on seriously addressing why many somalilanders want independence, the points they raise, to convince somalilanders why somalis should stick together etc I very rarely see anything like that, or it's stated very superficially. There is however a significant amount of hate, talks about financial benefit for somalia (berbera port etc), ideas pertaining to power and control. You can see that on discussions on this site.
