Kiddush Hashem on Wheels (Bina Magazine)

Today I read this article about a woman who is a Baalas Teshuva who wanted to attend the Bar Mitzvah of her nephew that was held at a reform temple. She and her husband rented an RV and parked it in the temple parking lot. after “services” she changed into sneakers to walk to the hall where had the reception, along with mixed dancing and music.

Then she says what a Kiddush Hashem it was, all the guests commented on how nice it was that she joined them despite their differences.

First of all, I thought that one is not allowed to enter a Reform temple. I think this was not an appropriate way to spend shabbos in an RV, with music and mixed dancing. Her husband missed tefillah btzibur (he davened beforehand in the RV) and the kids had to be farmed out.

why was this allowed and why is this an article in the Bina magazine? Will Reform Jews now point to this article and say “See, you CAN come to my bat mitzvah or whatever!”

I would appreciate some comments about this or feedback.
