Why is it, at this time of year, everyone and their chacha wants to 'enlighten' me about the heathen road to hell aka celebration of basant?

A couple of days ago, a teacher went on and on in a two-hour session about what is 'right' and what is 'wrong' and how Basant is 'wrong' and concluded by asking for a show of hands as to who prays five times a day.

As if that wasn't enough to get the blood boiling, just ten minutes ago, I had a pamphlet shoved into my car window (I'm closing those next time, no matter if I suffocate). Normally, I'd toss pamphlets right back out but the subheading caught my eye: "Basant: An invite to the wrath of Allah (swt)!". Curious, I read it. It seems there was a man who blasphemed against the Holy Prophet (PBUH) andhis daughter Fatima and this man was executed for this act. On the day of his execution, a man named Kaloo Ram (I'm not making this up), apparently decided it would be a great time to launch a festival and call it basant. So basically, celebrating/being happy/having fun on the death anniversary of an evil man being executed is unIslamic now. What next?
