Aray yaar, why are you blaming Noora, when the problem of sectarian hatred in the country runs much deeper?
It's not only LeJ that is killing Shia Muslims, it is also TTP, Jundullah, Jamat-ul-Ahrar and many other groups. They recruit from locals, they don't recruit internationally. The funding might be coming from India as well, also supported by NDS; but locals are being recruited. If there was sectarian harmony in the country, people wouldn't willing to be recruited, regardless of the funding from overseas. People are being recruited as there is a lot of sectarian hatred against Shias.
It is also evidenced by the posters on PDF: there is a lot of hatred against Shias. While I doubt any posters here would be involved in sectarian attacks in Pakistan, people that conduct attacks against Shias and other minorities have the same sectarian, divisive mindset; they just take it to a more extreme level.
