The OP may be right about his opinion, but the topic is highly arguable. Even with the worst market condition, some still managed to get hefty profits investing in altcoins. You can't really ask someone to stop doing something that fills up their bags. I think the OP just wants to emphasize how risky it is to invest in other coins other than bitcoin. But for me, a diversified portfolio is always better than only having bitcoin. Risk is always a factor when investing, we need to accept that, and mitigating it should be our top priority.
